Answer 1

Answer:

x = 39

Step-by-step explanation:

angle 1 + angle 2 = 180 degrees. (co int. angles are supplementary)

2x-8 + 3x-7 = 180

5x - 15 =  180

5x = 180 + 15

5x = 195

x = 39

Answer 2

question no 1 ka answer

1.

=2x + 3x = 90° {complementary angles sum up to 90 degrees}

5x = 90°

x = 90°/5

x = 18°

angles are: 36 and 54 degree
