Question

Three angles of a triangle are in the ratio 2:3:7. Workout the measurements of the angles.

Answer 1

Answer:

Step-by-step explanation:

let angles be 2x,3x,7x

2x+3x+7x=180°

12x=180

x=15°

the angles are 30°,45°,105°

Answer 2

Answer: 30°, 45° and 105° are the required angles.

Step-by-step explanation:

Given that the angles of a triangle is in the ratio 2:3:7

Let us assume that the angle are 2x, 3x and 7x

We know that the sum of the angles of a triangle is 180°

ie, 2x + 3x + 7x = 180

ie, 12x = 180

ie, x = 180/12

       = 15

Hence the angles are,

(i) 2x = 2 x 15 = 30°

(ii) 3x = 3 x 15 = 45°

(iii) 7x = 7 x 15 = 105°
