Question

Express both in degrees and radians, the angles of a triangle whosse angles are to each
other as 1:2:3

Answer 1

Answer:

Let the three angle be x, 2x and 3x

x+2x+3x = 180°

6x = 180°

x = 180°/6

x = 30°

1st angle = 30°

2nd angle = 2x

= 2*30°

= 60°

3rd angle = 3x

= 3*30°

= 90°

Hence, three angle of triangle are 30°, 60° and 90°.
