Question

the angles of a triangle are in the ratio 1:4:7.find their measures

Answer 1

HEYA ___ ✨✨

⏩ Sum of all angles in a triangle = 180°

Given the angles are in ratio 1:4:7

1x+4x+7x = 180

12x = 180

x = 180/12

x = 15

1(15)= 15°

4(15) = 60°

7 (15) = 105°

Answer 2

Answer:

Step-by-step explanation:

Let the angle be x, 4x,7x

Sum of all angle of triangle is 180

x+4x+7x=180

12x=180

x=180/12

x=15

4x=60

7x=105
