Question

What is the measure of angle 7?

suppose the measure of angle 6 can be represented be (2x-5). what equation can be written to solve the value of x?
what is the value of x?

Answer 1

The answer to this question is x=2.5

Answer 2

<7 = 47, 2x - 5 + 47 = 180, x = 69

Explanation:

<5 and <7 are vertical angles, which means that they have the same degree.

<7 + <6 = 180. <6 = 2x - 5. 2x - 5 + 47 = 180.

Solve

2x - 5 + 47 = 180

2x + 42 = 180

2x = 138

x = 69
