Question

One angle of a triangle is 60°. The other two angles are in the ratio of 3:5. Find these two angles?​

Answer 1

Answer:

let other two angles be 3x and 5x

60 + 3x + 5x = 180

8x. = 120

x = 15

other two angles are 45and 75

Answer 2

. let let the number 3x and 5 x

60° + 3x + 5x = 180°

60° + 8x = 180°

8x = 180° - 60°

8x = 120°

x = 120 / 8

x = 15°

3x = 3 × 15 => 45°

5x = 5 × 15 => 75°
