Question

Parallel lines r and s are crossed by transversal t to form 8 angles. Clockwise from top left, the angles formed with line r are blank, blank, 1, (2 x + 12.8) degrees; with line s are blank, blank, 117.6 degrees, blank.

What is the value of x?

Answer 1

2x+12.8=117.6

We move all terms to the left:

2x+12.8-(117.6)=0

We add all the numbers together, and all the variables

2x-104.8=0

We move all terms containing x to the left, all other terms to the right

2x=104.8

x=104.8/2

x=52+0.8/2

Answer 2

Answer:

24.8
