Question

One of the exterior angles of a triangle is 72 degree and its interior opposite angles are in the ratio 4:5. The angles of the triangle are​

Answer 1

Answer:

72 degree = 4x+5x

9x = 72

x = 8

4x = 32

5x = 40

other angle is ;

40+32+y=180

72+y=180

y=108

therefore,the angles are 32,40,108 degrees
