Question

If two complementary angles are in the ratio 13 : 5, then the angles are: a) 130, 50 b) 25o, 65o c) 65. 25 d) 65o, 35o​

Answer 1

Answer:

Given that the ratio of two complementary angles is 13:5.  

Let the angles are13x and 5x

We know, 13x+5x=90o

⇒x=5

Therefore, the angles are 65o and 25o.

Step-by-step explanation:

Answer 2

Sum of complementary angles = 90°

Let the angles be 13x and 5x

13x + 5x = 90°

18x = 90°

x = 90/18

x = 5

Angle 13x = 13 × 5 = 65

Angle 5x = 5 × 5 = 25

so the answer is 65°, 25°
