Question

in triangle ABC, angle A: angle B: angle C = 5:7:8 . find the measure of each angle of triangle ABC​

Answer 1

Answer:

A = 45, B = 63, C = 72

Step-by-step explanation:

Let the values of all angles = 5x, 7x, 8x respectively

It is known that adding all of the angles in a triangle = 180

5x + 7x + 8x = 180

20x = 180

x = 180/20

= 9

Angle A = 5x = 5*9 = 45 degrees

Angle B = 7x = 7*9 = 63 degrees

Angle C = 8x = 8*9 = 72 degrees.

Hope this helps! :)
