Question

What does x equal?
Thanks!

Answer 1

Hi there!

The answer to this question is x=79

Explanation:

using the triangle sum theorem

you know all angles add up to 180

so in other words: x+(x-17)+39=180

then you simplify: 2x=158

x=79

Answer 2

X+x-17+39=180
2x+22=180
Subtract 22 from both sides
2x=158
X= 79
