Second question (find
Total angle on a straight line is 180 °
(3x-28)+90+(66-x)=180
2x + 128 =180
2x = 180 - 128
2x = 52
Divide through by 2
x = 26

(3x-28)+but x=26
[3(26)-28] + (78-28) + 50 +

First Question (find the value of x)

(4x-8)+34+(76-x)=180
3x + 102 =180
3x =180 - 102
3x = 78
Divide through by 3
x=26
Therefore x = 26
