Question

Someone please help I’m failing and I need it and include explanation please!

Answer 1

X=18

Explanation:

This is on a straight line, which is 180° in total.

Information:

106°

4x

On a straight line

106+4x=180

Subtract the 106 from 180 to cancel it out.

4x=74

Divide 4 to both sides to single the x out

x=18.5
