Question

If the angles of a triangle ABC are in the ratio 1:2:3 find the measures of A, B &C * A) 60, 30, 90 B) 30, 60, 90 C) 90, 30, 60 D) 40, 50, 90

Answer 1

Answer: B) 30, 60, 90

Step-by-step explanation:

Let the common multiple be 'x'.

In a triangle,

Sum of all angles = 180

1x + 2x + 3x = 180

6x = 180

x = 30

Angle A = x = 30

Angle B = 2x = 2*30 = 60

Angle C = 3x = 3*30 = 90
