Find the angles​

Answer 1

Answer:

80 degrees and 280 degrees

Answer 2

Answer:

40° and 140°

Step-by-step explanation:

The ratio of the supplementary angles is 2:7

Let the angles be 2x and 7x

As the angles are supplementary

So,

2x + 7x = 180°

9x = 180°

x = 180° ÷ 9

x = 20°

Now,

2x = 2×20°

=40°

7x = 7×20°

= 140°

So,

2x = 40°

7x = 140°
