Question

The three angles of triangle are in ratio 1:2:1. Find all the angle of

the triangle.​

Answer 1

Answer:

45°, 90° and 45°.

Step-by-step explanation:

let the angles be 1x,2x and 1x. Now,

Sum of all the angles in a triangle = 180°

1x + 2x + 1x = 180

=> 4x = 180

=> x = 180/4

=> x = 45

Hence the measure of the angles in the triangle are (1 x 45)° = 45°, (2 x 45)° = 90° and (1 x 45)° = 45°, respectively.
