Question

If the angles of a triangle are in the ratio 1:4:5, find the angles.
​

Answer 1

Let the main ratio be x

Hence, the main angles will be: x, 4x, and 5x

A/Q,

x + 4x + 5x = 180 (Angle Sum Property of a triangle)

10x = 180

x = 180/10

x = 18

Hence, angles formed:-

x = 18

4x = 4 x 18 = 72

5x = 90

THEREFORE THE ANGLES ARE (18, 72, 90) degree

Answer 2

Answer:

18°, 72° and 90° respectively

Step-by-step explanation:

let the angles of the triangle be 1x , 4x and 5x.

now, the sum of the three interior angles of a triangle = 180°

so, 1x+ 4x+5x=180

10x=180

x=18°

1x=18°

4x=72°

5x=90°
