Question

the angle of a triangle in the ratio 2;5:8. find the angle​

Answer 1

Answer:

Let the common angle be x.

So angles are 2x, 5x, 8x.

Sum of all angles of a triangle = 180⁰

2x+5x+8x=180⁰

15x=180⁰

x=180⁰/15

x=12⁰

Angles are 2×12⁰=24⁰, 5×12⁰=60⁰, 8×12⁰=96⁰.

Answer 2

Answer:

By ASP

Angle A + Angle B + Angle C

2x + 5x + 8x = 180°

15x = 180°

x = 180°/15

x= 12°

So, Angle A = 2x = 2 × 12 = 24°

Angle B = 5x = 5 × 12 = 60°

Angle C = 8x = 8 × 12 = 96°
