Question

What is the value of w?

Answer 1

Answer: W = 34°

Explanation:

Use the angle sum theorem!

2w + 2w + 1 + 43 = 180

4w + 44 = 180

4w = 136

w = 34

Answer 2

w = 34°

Explanation:

the sum of the 3 angles in a triangle = 180°

sum the 3 angles and equate to 180

2w + 1 + 2w + 43 = 180 , that is

4w + 44 = 180 ( subtract 44 from both sides )

4w = 136 ( divide both sides by 4 )

w = 34
