Question

Angle 3 is 65 degrees. solve for x if angle 5 is equal to 5x.

Answer 1

X=23

Explanation:

If angle 3 measures 65 degrees the so does angle 2, 7 and 6. By the definition of parallel lines. Then by the definition of supplementary lines angle 5+ angle 7=180 degrees, so 5x+65=180 => 5x=115 =>
`(5x)/(5)`=
`(115)/(5)` => x=23.
