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

mark as brainliest :)
