Answer:
50 , 50 , 80
Step-by-step explanation:
let the third angle be x
we know
somat is 180°
x/2+10 + x/2+10 + x = 180
x+20+x+20+2x / 2 = 180 ........(taking lcm of denominator)
4x+40/2 = 180
4x + 40 = 180 × 2
4x + 40 = 360
4x = 360 - 40
4x = 320
x = 320/4
x = 80
third angle. is 80
sec ang = fir ang = x /2 + 10 = x + 20 / 2 = 80 + 20 / 2 = 100 / 2 = 50
