Question

What is the value of x?
*Hint - you'll get a decimal!

Answer 1

x = 55.7

Explanation:

the angle vertically opposite (2x - 3)° is congruent

Then

(2x - 3)° and (x + 15.9)° are same- side interior angles and sum to 180°, so

2x - 3 + x + 15.9 = 180

3x + 12.9 = 180 ( subtract 12.9 from both sides )

3x = 167.1 ( divide both sides by 3 )

x = 55.7
