What is the greatest possible whole number value of a congruent side lengths?
A. 9cm
B. 10cm
C. 14cm
D. 15cm
Answer:
C. 14cm
Step-by-step explanation:
The square of the longest line, in an obtuse triangle, is greater than the sum of the squares of the other two sides. So it is appropriate for equivalent legs to have a length
L^2 + l^2=2l^2
14^2+14^2=20^
196+196=400
392=400 400
The result: 14cm

Had the test
The expressions are also equal to 1/3 is cos (90 -x).
What is Complementary Properties of Trigonometry?These relations are valid for all the values of A that lies between 0° and 90°.
sin (90°- A) = cos A ; cos (90°- A) = sin Atan (90°- A) = cot A; cot (90°- A) = tan Asec (90°- A) = csc A; csc (90°- A) = sec AGiven:

A 12 ft ladder is leaning against a wall with an angle of elevation of 31.2 degrees. How high up the wall will the ladder reach? Round to the nearest tenth and show work..
Answer:
12/sin90'=b/sin67'
12sin67'=bsin90'
b=12sin67/sin90'
Step-by-step explanation:
sister ,we can use the law of sines. since we have the angle of elevation and assume the wall makes a right angle with the ground, our angle opposite the ground is 180-[90+23=67

How many unique triangles can be formed with two side lengths of 10 centimeters and one 40° angle?
Enter a number in the box.
Answer:
2 unique triangles
Step-by-step explanation:
We can only form two triangles
Since two of the sides are equal, we can form two isosceles triangles
The first one will have 10, 10 , the last side, then 40, 70 , 70 as the internal angles
Just note that the angles must add up to be 180 and that there are two equal angles as we are dealing with an isosceles triangle
The second form is 10, 10 , 40 , 40 and 100
Here, we have the 40 on the sides of the base of the isosceles triangle with the measure 100 being the last angle
The number of unique triangles that can be formed with he given parameters are; 2
We are told that;
Two side lengths of the triangle = 10 cm
One angle = 40°
This means the that the triangle can be an isosceles triangle.Now, the two equal angles could be 40° each.
Sum of angles in a triangle = 180°Thus;
Third angle of the triangle = 180 - 2(40) = 100°
Now,if we assume that the 40° is not the equal angle, then it means that the equal angle will be;(180 - 40)/2 = 140/2
>> 70°
Thus, we can make 2 unique isosceles triangles.

if MNP = 107, what is NMQ
The measure of angle NMQ is 73 degrees
The given parameter is:
[tex]\angle MNP = 107[/tex]
From the given figure, angles MNP and NMQ are adjacent angles.
Given that the adjacent angles of a trapezoid add up to 180 degrees.
We have the following equation
[tex]\angle MNP + \angle NMQ = 180[/tex]
Make NMQ the subject
[tex]\angle NMQ = 180 -\angle MNP[/tex]
Substitute 107 for MNP
[tex]\angle NMQ = 180 -107[/tex]
[tex]\angle NMQ = 73[/tex]
Hence, the measure of angle NMQ is 73 degrees

Gabby needed to type up 12 documents during the week. By Wednesday, she only finished 3 1/5 documents. On Thursday, she finished another 5 3/4 documents. If she finished writing all documents by Friday, how much did she write on Friday?
Answer: She wrote [tex]3\dfrac{1}{20}[/tex] documents on Friday.
Step-by-step explanation:
GIven: Total documents needed to be done = 12
If she finished writing all documents by Friday, then the number of documents written on Friday = 12-(work done by Wednesday) - (work done on Thursday)
[tex]= 12 -(3\dfrac15)-(5\dfrac34)\\\\=12-\dfrac{16}{5}-\dfrac{23}{4}\\\\=\dfrac{12\times20-16\times4-23\times5}{20}\\\\=\dfrac{240-64-115}{20}\\\\=\dfrac{61}{20}\\\\=3\dfrac{1}{20}[/tex]
Hence, She wrote [tex]3\dfrac{1}{20}[/tex] documents on Friday.

Question 7 of 10
What is the solution to this equation
Answer:
x = 4
Step-by-step explanation:
x + 4(x+5) = 40 (Given)
x + 4x + 20 = 40 (Distribute the 4 into the x and 5)
5x + 20 = 40 (Add like terms)
5x = 20 (Subtract 20 on both sides)
x = 4 (Divide 5 on both sides)
The extended ratio of the sides of a triangle is 7:8:10. The perimeter of the triangle is 275 cm. How many centimeters is the LONGEST side of the triangle?
Answer:
Longest side = 110 cm
Step-by-step explanation:
The extended ratio of the sides of a triangle is 7:8:10
Let sides are 7x, 8x and 10x.
The perimeter of the triangle is 275 cm.
Perimeter of a triangle = sum of all sides
7x+8x+10x = 275
25x = 275
x = 11
Longest sides of the triangle = 10x
= 10 (11)
= 110 cm
So, the longest side of the triangle is 110 cm.

Answer:
M x 1/3 + 2. The variable is Marcella's age. If Marcella is 63, one third of her age is 21 so 21+2 = Justin is 23. Aimee is 23x2-4 so she is 62 years old.

Answer:
perpendicular
Step-by-step explanation:
a line is perpendicular to another line when m of one line is the negative or opposite reciprocal of the other. m= 2
the perpendicular lines for that would be 1/2 which is the reciprocal and then the opposite sign which is negative.

HELP NOW PLEASEEEEEEEEEEEE ANSWER NEEDS TO B POSITIVE
Answer:

Step-by-step explanation:
So first we do (x^5)^2 which we know is just x^10 because of exponents of powers I believe it's called, basically you just multiply the two powers.
Then you do the bottom half which is x^3 * x^7 and that equals x^10 because of the product of exponent rule,
Then we do x^10/x^10 which = 1 because the same number over the same number is always 1.
Let me know if you have any questions
Answer:
Solving the expression: [tex]\frac{(x^5)^2}{(x^7)(x^3)}[/tex] the answer is 1
Step-by-step explanation:
We need to solve the expression: [tex]\frac{(x^5)^2}{(x^7)(x^3)}[/tex]
We know that exponent rule: [tex](a^m)^n=a^{m*n}[/tex]
Applying this rule in numerator
[tex]\frac{(x^5)^2}{(x^7)(x^3)}\\=\frac{(x^{5*2})}{(x^7)(x^3)}\\=\frac{(x^{10})}{(x^7)(x^3)}[/tex]
We know the exponent rule: [tex](a^m).(a^n)=a^{m+n}[/tex]
[tex]=\frac{(x^{10})}{x^{7+3}}\\=\frac{(x^{10})}{x^{10}}[/tex]
Now, using the exponent rule: [tex]\frac{a^m}{a^n}=a^{m-n}[/tex]
[tex]=x^{10-10}\\=x^0[/tex]
We know that [tex]a^0=1[/tex]
So, [tex]x^0=1[/tex]
Solving the expression: [tex]\frac{(x^5)^2}{(x^7)(x^3)}[/tex] the answer is 1
