Question

One of the angle of the triangle is equal to the sum of the other two angle. If the ratio of the other two angle is 4:5 Find the angle of the triangle​

Answer 1

Step-by-step explanation:

LET THE THREE ANGLES BE

1. X
2. 4X
3. 5X

THEN THE SUM OF THREE ANGLES WILL BE =

${180}^{o}$

OR , X+5X+4X=180

OR, 10 X = 180

OR,

$\frac{180}{10}$

therefore

X = 18

4X = 18*4=72

5X = 18*5=90
