Question

one of the angles of a triangle is equal to the sum of the other two angles. if the rstio of thr other two angles is 4 : 5, find the angles of the triangle.​

Answer 1

Answer:

Step-by-step explanation:Let the ratio be 4y:5y.Let the other angle be x.

Given that 4y+5y=x ....(1)

By angle sum property,

4y+5y+x=180

2x=180

x=90

y=10

So the angles are 90,50,40
