Answer:60,80,40
Step-by-step explanation:
Sum of angles of a triangle = 180 degree
x - 40 + x - 20 + 1/2 x - 10 = 180
2x + x/2 - 70 = 180
4x+x/2 = 180+70=250
5x/2 = 250
5x = 250*2 = 500
x = 500/5 = 100
Angles are:
x-40 = 100-40 =60
x-20 100-20 = 80
1/2 x - 10 = 50 -10 = 40
60 degree, 80 degree, 40 degree
