Question

Given that line f is parallel to line g, find the value of x. The diagram is not to scale.

Answer 1

@apple_pi

Answer 2

the angles are cointerior and add to 180

so use that fact to find x

3x + 6x + 45 = 180

just collect like terms and then solve for x

Answer 3

Yeah what @campbell_st said. Cointerior means they are on the same side of the transversal (cutting line) of 2 parallel lines. And cointerior angles ALWAYS add up to 180.
