Question

if the angles of a triangle are in the ratio 1:2:6 then find the measure of the angle
​

Answer 1

Answer:

20° , 40° , 120°

Step-by-step explanation:

Given , the angles of a Triangle ABC are in the ratio 1:2:6

Let ∠A = 1x  ∠B = 2x  ∠C = 6x  

In a Triangle ∠A + ∠B + ∠C = 180°

1x + 2x + 6x = 180

9x = 180

x = 180 ÷ 9 = 20

The angles are,

20° [ 1 × 20 ]

40° [ 2 × 20 ]

120° [ 6 × 20 ]
