Question

Given 1 || m
11
n, find the value of x.
m
(8x-20)
(3x+2)
→n

Answer 1

x=18

Explanation:

They are on a straight line which means they add to 180 and a more precise term, they form a supplementary angle

so knowing that we apply the principal

(8x-20) + (3x+2)=180

8x-20+3x+2=180

8x+3x=180+20-2

11x/11=198/11

x=18

Therefore x=18
