Question

In a triangle angle A : angle B :angle C = 5:7:8. Find the measure of each angle of triangle ABC.

Answer 1

Answer:

let angle be x

5x+7x+8x=180

=20x=180

2x=18

x=9

angle a = 45

angle b = 63

angle c = 72

Answer 2

Answer:

let angle be x

5x + 7x + 8x = 180

20 = 180

x = 180/20

x= 9

angle A = 45

angle B = 63

angle C = 72
