Question

Two lines are intersecting. What is the value of x? Enter your answer in the box. (x + 23) (2x + 4)° Help! Please!!!

Answer 1

`x = 51^o`

Explanation:

Given

Intersecting lines

Required

Find x

To do this, we make use of:

`x + 23^o + 2x + 4^o = 180^o` --- angle on a straight line

Collect like terms

`x + 2x = 180^o - 4^o - 23^o`

`3x = 153^o`

Divide both sides by 3

`x = 51^o`
