Question

2 angles of a triangle are in ratio 4:5 if the sum of these angles is equal to the 3rd angle find the angles of the triangle

Answer 1

Let the first angle be 4a
Second angle = 5a
Third angle = 9a

4a +5a +9a = 180
=> 18a = 180
=> a = 10

First angle = 40°
Second angle = 50°
Third angle = 90°
