Question

Two supplementary angles are in the ratio of 2 : 3. The angles are :(a) 76°,114°
(b) 72°, 108°
(c) 70°, 105°
(d) 66°,99
​

Answer 1

Answer:

72°, 108°

Step-by-step explanation:

Let the measure of two angles be 2x° and 3x°. So sum of two supplementary angles = 180°

2x + 3x = 180°

5x = 180°

=> x = 36°

Required angles

2x = 2 x 36° = 72°

3x = 3 x 36° = 108°.
