Answer:
(2x+20°) = 76
(x+30°) = 58
(2x-10°) = 46
Step-by-step explanation:
Sum of 3 angles of a triangle should be equal to 180°
So, sum of (2x+20°) , (x+30°) and (2x-10°) should be 180°
(2x+20°) + (x+30°) + (2x-10°) = 180
2x+ 20° + x+ 30° + 2x-10° = 180
5x + 40 = 180
5x = 180 - 40
5x = 140
x = 140/5
x = 28
Now the 3 angle of triangle are :
(2x+20°) = 76
(x+30°) = 58
(2x-10°) = 46
