Question

Solve for x.
3x + 13,
H
6x +
x = [?]
Enter

Answer 1

Explanation:

you know some things about the two angles they are the complimentary parts of just one of those perpendicular lines. so you can say

180 = (6x + 5) + (3x+13)

180 = 9x +18

162 = 9x

18 = x

Answer 2

Solution given;

6x+5+3x+13=180(sum of exterior angle is 180°)

9x=180-18

x=162/9

x=18 is a required answer.
