Question

3. If two complementary angles are in the ratio 10 : 8, then the angles are: (a) 50°, 40° (b) 100°, 80° (c) 60°, 30° (d) 65°, 25°​

Answer 1

Answer:

Option A ✅

Step-by-step explanation:

Given :-

Two complementary angle are in ratio 10 : 8

To Find :-

Angles

Solution :-

Let,

Angle 1 = 10x

Angle 2 = 8x

We know that,

Sum of two complementary angle are 90⁰

10x + 8x = 90

18x = 90

x = 90/18

x = 5

Angles are

10x = 10(5) = 50⁰

8x = 8(5) = 40⁰

Hence,

Option A is correct
