Question

Two Parallel Lines l and M are cut by a transversal T if the interior angles of the same side of t b (2 x -8 )degree and (3 x-7) degree find the measure of each of these angles

Answer 1

2x-8+3x-7=180
5x-15=180
5x=180+15
5x=195
x=195/5=39

Answer 2

(2x-8)+(3x-7) = 180

2x-8+3x-7 = 180

5x -15 = 180

5x = 180 +15

5x = 195

x= 195/5

x= 39

so, (2x-8)= 2×39-8 = 78-8=70°

(3x-7) = 3×39 -7= 117-7=110°

hope this answer help you..
