11. You are asked to put a V-shaped roof on a house. The slope of the roof is 53°. What is the measure of the angle needed at th
Anestetic [448]
The question said that it told you the base angles. A roof would have two equal base angles. The base angles= 53

All the angles of a triangle each 180, (the roof is shaped like a triangle)

So, let's make x the missing angle.

53(2)+x=180

106+x=180

Subtract 106 on both sides.

180-106= 74

The vertex angle is 74.

I hope this helps!

The product of two numbers is 20. If one of the numbers is 4/7 what is the other number?
TiliK225 [7]

Answer:

35

Step-by-step explanation:

1. Translate the question into an equation:

  • \frac{4}{7}x = 20

2. Multiply both sides by 7/4.

  • \frac{4}{7}x * \frac{7}{4} = 20 * \frac{7}{4}
  • x = \frac{140}{4}
  • x = 35
