Question

two supplementary angles are in the ratio 2:7 .find the measure of angles
​

Answer 1

Answer:

Step-by-step explanation:

TWO ANGLES BE 2 X AND 7 X

2 X+7 X = 180

9 X = 180

X = 20

THEREFORE THE ANGLES ARE 40 AND 140.

Answer 2

Answer:

Then, ratio becomes  2:7

As , their sum should be 180°,

⇒2x + 7x = 180°

⇒9x = 180°

⇒x = 180 ÷ 9

⇒x = 20

So, the angles are ,

2x = 2 * x = 2*20 = 40°

7x = 7 * x = 7 * 20 = 140°

We can verify by adding them , as 140+40 = 180°

Answer : hence, the angles are 40° and 140°.
