Question

Find the measure of the larger angle. 22.5° 52.5° 127.5° 180°

Answer 1

Remark

I think we are to assume that the line is a straight one and that it contains a total of 180o at the intersection.

Equation

2x + 7 + 6x - 9 = 180o

Solve

Combine the like terms on the left.

2x + 6x + 7 - 9 = 180

8x - 2 = 180o Add 2 to both sides.

8x - 2 + 2 = 180 + 2

8x = 182 Divide by 10

8x/8 = 182/8

x = 22.75

But that is not the answer.

You need to find 6x - 9

Angle = 6x - 9

Angle = 6*18.2 - 9

Angle = 127.5 <<<<< Answer.
