The difference between the largest and the smallest angles of a triangle whose angles are in the ratio of 5 : 3 : 10 is
-
- 20°
- 30°
- 50°
- 70°
- 20°
Correct Option: D
On the basis of given question , we have
In ∆ABC,
A : B : C = 5 : 3 : 10
We know that sum of all three angles of triangle is 180°
i.e. ∠A + ∠B + ∠C = 180°
Sum of the terms of ratio = 5 + 3 + 10 = 18
| ∴ Required difference = |  |  | × 180 = 70° | |
| 18 |
