Answer 1

Answer:

A linear pair of angles is formed when two lines intersect. Two angles are said to be linear if they are adjacent angles formed by two intersecting lines. The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.

so supplementary

Answer 2

Answer:

7x= 12*7= 84° =angle 1

8x = 12*8=96° = angle 2

Step-by-step explanation:

Let Angle 1 = 7x

Angle 2=8x

Sum of 2 angles in a linear pair is 180°

Therefore, Angle 1 + Angle 2 = 180°

7x + 8x = 180°

15x = 180°

x = 180°/15

x = 12

7x= 12*7= 84° =angle 1

8x = 12*8=96° = angle 2

84°+96°= 180°
