Question

The angles of a triangle are,3x,(2x+20) and (5x-40). Find the angles.

Answer 1

Answer:

sum of angles of triangle =180

3x+(2x+20)+(5x-40)=180

10x-20=180

10x=180+20

10x=200

x=200/10=20

angles are 3(20), (2(20) +20), (5(20) -40)

angles are 60, (40+20), (100-40)

angles are 60,60,60
