Answer:
m∠I = 45.2°
Step-by-step explanation:
From the picture attached,
By applying cosine rule in in ΔHIJ,
Cos(∠I) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
= [tex]\frac{JI}{HI}[/tex]
= [tex]\frac{62}{88}[/tex]
m∠I = [tex]cos^{-1}(\frac{62}{88})[/tex]
= 45.21
= 45.2°
Therefore, 45.2° will be the correct option.

which statement is true about the congruent triangles below? URGENT
Answers
Answer:
LN = HJ
Step-by-step explanation:
If you look at the two triangles, you will see each side has a different number of lines on them. Each set of lines corresponds to the same set of lines on the other triangle.
So since side IH has one line the side on the other triangle with one line would be congruent. So that would be line ML.
Also if there are not lines on every side then you could identify the triangle by the red square in the corner meaning that that is a right angle (90 degrees.)

Z is the intersection of the triangles ______
Answers
Answer:
Circumcenter of a triangle is formed by joining the perpendicular bisectors of three sides of triangle.
As we draw perpendicular bisectors of three sides, they will intersect at one point(say O) which lies inside the circle.
From that point of intersection, draw a circle touching each of the vertex of a triangle and we get a circumcircle. And O becomes centre of the circle.
Hence, circumcenter lies inside the triangle.
Point Z is the intersection of the medians. Then the correct option is A.
What is the triangle?The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180°.
Z is the centroid of the triangle ΔUVW.
The circumcenter of a triangle is framed by joining the opposite bisectors of three sides of the triangle. But the perpendicular bisectors are not shown.
The opposite sides are bisects. Then point Z is the intersection of the medians.
Thus, the correct option is A.

There are three 20.0 Ω resistors connected in series across a 120 V generator. What is the voltage drop across one of the resistors?
Answers
Answer:40v
Step-by-step explanation:
The voltage that drop across one of the resistors when the battery is given is to be considered as the 40 volts.
Calculation of the voltage:
Since There are three 20.0 Ω resistors connected in series across a 120 V generator.
So here Total current be like
[tex]= 120 \div (20 \times 3)\\\\= 120 \div 60[/tex]
= 2
Now the drop in the voltage is
= (2) (20)
= 40 volts
hence, The voltage that drop across one of the resistors when the battery is given is to be considered as the 40 volts.

38.5g of sugar is needed to make 5 cakes. How much sugar is needed for 7 cakes?
Answers
Answer: 53.9g
Step-by-step explanation:
As you can't end up with a whole number by doing 7 divided by 5, first work out how much sugar is needed for 1 cake.
To find out how much sugar is needed for 1 cake, divide both sides by 5:
5 / 5 = 1
38.5 / 5 = 7.7
Therefore 7.7g of sugar is needed to make 1 cake.
Now times each value by 7 to get the answer :
7.7 x 7 = 53.9g
1 x 7 = 7
Therefore, 53.9g of sugar is needed.
Answer:
53.9g
Step-by-step explanation:
38.5 / 5 as there are 5 cakes
this will give you the amount of sugar needed for 1 cake, so you X by 7 to find out how many for 7 cakes
38.5 / 5 = 7.7
7.7 X 7 = 53.9g
Select one the restricted domains of f(x)=(8−2x)2 that will make the inverse of f(x) a function. There may be more than one.
Answers
Answer:
[tex]x\leq 4[/tex] or [tex]x\geq 4[/tex]
Step-by-step explanation:
We are given that
[tex]f(x)=(8-2x)^2[/tex]
We have to find the restricted domain of f which make the inverse of f.
Substitute x=4
[tex]f(4)=0[/tex]
One-to-one function:
The function is called one-to-one when
[tex]f(x_1)=f(x_2)[/tex] for [tex]x_1=x_2[/tex]
The function is one-to-one when [tex]x\leq 4[/tex] or [tex]x\geq 4[/tex]
When the function is one-to-one then the function has inverse function.
If the function is not one-to-one then function has no inverse .
Therefore, the restricted domain of f which make the inverse of f(x) a function is given by
[tex]x\leq 4[/tex] or [tex]x\geq 4[/tex]

Answer:
85 degrees
Step-by-step explanation:
In similar triangles, corresponding angles are congruent, or have the same measure.
Therefore, angle B must also be 56 degrees. In a triangle, there are 180 degrees.
