Question

the supplemqntary angles are in the region 2:7 find the angle​

Answer 1

For example 100° and 80° are supplementary angles because their sum is 180°. Now,coming to the question , Let the common multiple of each term of ratio be x. Answer : hence, the angles are 40° and 140°.

Answer 2

Answer:

40° , 140°

Step-by-step explanation:

let the 1st angle be 2x and the 2nd angle be 7x

A/Q,

2x + 7x = 180°

9x = 180°

x = 180°/9

x = 20°

so, 1st angle = 2x = 40°

2nd angle = 7x = 140°

NOTE:

• sum of supplementary angles = 180°
