Question

Find the value of x . Show your steps.
X =
2
83°
(12x + 1)º

Answer 1

(12x+1)°+83°=180°(Two reasons were used Corresponding angles and angles on the same straight line)

`12x+1+83=180\\12x=180-83-1\\12x=96\\(12x)/(12) =(96)/(12) \\x=8`

∴x=8°

Answer 2

8

Explanation:

180-83 = 97

97 = (12x+1)

96 = 12x

x= 8

You are able to do this because the angle to the left of 83 degrees is parral to (12x+1) meaning they should have the same degrees.
