Question

One angle of a triangle is equal to the sum of the other two angle . if the other two angle are in the ratio of 4:5 find the three angle

Answer 1

Hello Dear!!!

Here's your answer....

The angles are in the ratio - 4:5

Let,

The angles be 4x and 5x

And sum of these angles is third angle

Third angle is 4x+5x

Third angle is 9x

Sum of all angles in a triangle is 180

9x + 4x + 5x = 180

18x = 180

x = 180/18

x = 10

Then angles are

4x = 4(10)
= 40

5x = 5(50
= 50

9x = 9(10)
= 90

Angles are 40,50,90
