Question

EXERCISE 17A
1. Two angles of a triangle are in the ratio 2:3 and third angle is 60". Find the other two angle
of the triangle
​

Answer 1

Let the other two angles be 2x and 3X

2x + 3x + 60 = 180

NOW FIND THE VALUE IF X.

SO X= 24

HENCE 2×24=48

3×24=72

Answer 2

Answer:

48,72

Step-by-step explanation:

let the ratio be 2x and 3x

2x +3x + 60= 180    (angle sum property)

5x+ 60= 180

5x=180-60

5x = 120

x=120/5

x=24

2x =2*24= 48

3x=3*24= 72
