Question

two supplementary angles are in the ratio of 5:7.find the angles​

Answer 1

Answer:

75° and 105°

Step-by-step explanation:

sum of supplementary angles = 180°

given they are in the ratio of 5:7

Let 5x & 7x are the angles.

sum of angles = 180

5x+7x = 180

12x = 180

x = 180/12

x =15

First angle, 5x = 5×15 =75°

second angle, 7x = 7×15 =105°
