Answer:
the measure of angle 4 is 52 degrees.
Step-by-step explanation:
The measure of angles 3 and 4 added together is 90 degrees. Angle 3 is 38 degrees. 90-38=54.
Answer:
∠ 4 = 52°
Step-by-step explanation:
The 3 angles lie on a straight line and sum to 180°, that is
90 + ∠ 3 + ∠ 4 = 180, substitute ∠ 3
90° + 38° + ∠ 4 = 180°
128° + ∠ 4 = 180° ( subtract 128° from both sides )
∠ 4 = 52°

Answer:
the value of x is 5/7 which is in fraction
Answer: x = 5/7
Step-by-step explanation: 2x/3 + x/2 =5/6
To use a least common denominator, divide LCD by the original denominator and multiply the original numerator by the result.
for 2x/3 6÷3=2 2×2x=4x so that becomes 4x/6
for x/2 6÷2=3 3× (invisible) 1 = 3x, so that becomes 3x/6
combine 4x/6 + 3x/6 = 7x/6
Back to the original equation, substituting the calculated term:
7x/6 = 5/6 Multiply both sides by 6 to simplify (6)(7x/6) = (6)(5/6) 6's "cancel"
7x = 5 . Divide both sides by 7 to solve for x 7x/7 = 5/7
x = 5/7

If a rectangle is (x+2) wide and (x-7) in length, the area of the rectangle is?
Answers
Answer: x² - 5x - 14
Step-by-step explanation: Start with the formula for the area of a rectangle.
Area = length x width
To multiply these two binomials, let's use the F.O.I.L. method.
The product of the first terms is x².
The product of the outer terms is -7x.
The product of the inner terms is 2x.
The product of the last terms is -14.
So we have x² - 7x + 2x - 14 which simplifies to x² - 5x - 14.

How can I split 166 in half
Answers
You divide 166 by 2. The answer would be 83.
The value of splitting 166 in half gives two equal halves of 83 each.
When 'split' a number in half, dividing the number into two equal parts.
Here want to split the number 166 in half.
Perform a division operation by dividing 166 by 2.
Division is the opposite operation of multiplication.
When divide a number by 2, you are essentially finding the value of half of that number.
So, the calculation is as follows:
166 ÷ 2 = 83
This means that half of 166 is 83.
Divide the number 166 into two equal parts, each being 83.
If add both halves together, you get the original number back:
83 + 83 = 166
Therefore, dividing 166 by 2 allows to splitting it equally into two halves, each having a value of 83.

If tan(x)=3/5 and sin(x)>0, what is sin(2x)?
With STEPS PLEASE AND NO TROLLING.
Answers
i edited the answer. hope it helps. if it isn't ryt tell me plz
Answer:
sin2x = [tex]\frac{30}{34}[/tex]
Step-by-step explanation:
Given
tanx = [tex]\frac{3}{5}[/tex] = [tex]\frac{opposite}{adjacent}[/tex]
This is a right triangle with legs 3 and 5
Let the hypotenuse be h , then using Pythagoras' identity
h² = 3² + 5² = 9 + 25 = 34 ( take the square root of both sides )
h = [tex]\sqrt{34}[/tex]
Thus
sinx = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{3}{\sqrt{34} }[/tex]
cosx = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{5}{\sqrt{34} }[/tex]
Hence
sin2x = 2sinxcosx = 2 × [tex]\frac{3}{\sqrt{34} }[/tex] × [tex]\frac{5}{\sqrt{34} }[/tex] = [tex]\frac{2(3)(5)}{\sqrt{34}(\sqrt{34}) }[/tex] = [tex]\frac{30}{34}[/tex]
