One angle of a triangle is 60. The other two angles are in the ratio 3/2:4/3. Find these angles

Answer»

FIRST ANGLE of a triangle=60

Let the SECOND angle be=3/2x

Let the third angle be=4/2x

sum=180degree(sum of ANGLES of a triangle)

A.T.Q.

60+3/2x+4/2x=180

3/2x+4/2x=180-60

7x/2=120

x=120×2/7

x=140/7

x=20
