Question

if two supplimentery angles are in ratio 2:7 then the angles are?​

Answer 1

Answer:

2×20=40degree

7×20=140degree

hope it helps you.. if it does plz mark me brainliest

Answer 2

let the common ratio be as x

→ 2x and 7x

Now , 2x + 7x = 180° ...(since these angles are supplementary)

9x = 180°

x = 180°/ 9

x = 20°

hence, the measure of angle x is 20 degree

• 2x = 2 × 20 = 40°
• 7x = 7 × 20 = 140°

therefore , the angles are 40° and 140° respectively...
