Question

angles in a linear pair are in the ratio 4.5. what is the measure of each angle?​

Answer 1

Let the angle be 4x and 5x

4x + 5x = 180°

9x = 180°

1st angle = 4x = 4 × 20 = 80°

2nd angle = 5x = 5 × 20 = 100°

Hope it helps you

Good morning have a great day ahead

Answer 2

Answer:

Angle 1 = 80°

Angle 2 = 100°

Step-by-step explanation:

Ratio= 4:5

Let 1st angle be 4x

Let 2nd angle be 5x

.

4x + 5x = 180° (Linear pair)

.

9x = 180°

.

x = 180°÷9

.

x = 20°

.

.

.

As we supposed Angle 1st was 4x. So, 4×20°=80°

.

And 2nd Angle was 5x. So, 5×20°=100°
