Question

5. Two supplementary angles are in the ratio 4:5. Find the angles.​

Answer 1

Answer:

The supplementary angles are 80 degrees and 100 degrees

Step-by-step explanation:

4x+5x=180

9x=180

x=180/9

x=20

Answer 2

Solution:-

Let angles are 4x & 5x.

∴ Angles are supplementary

∴ 4x + 5x = 180°

⇒ 9x = 180°

⇒ x = 180°/9 = 20°

∴ Angles are 4 × 20° , 5 × 20°

⇒ 80°& 100°
