Question

One angle of a triangle is equal to the some of the other to. If the ratio of other two angles is7:8 find the angles of the triangle.

Answer 1

Let the angles be x

Sum of all the triangle is 180

(one angle is equal to the sum of other to)
180=7x + 8x +15x
180=30x
6=x

Angles of triangles

One angle =42
Second angle =48
Third angle=90

Answer 2

Let the ratio be x
So
7x, 8x
Third angle =15x

7x+8x+15x=180
30x=180
X=6

7x=7*6=42
8x=8*6=48
15x=15*6 =90





I hope this will help you
