Answer 2

Answer:

53° , 57° and 70°

Step-by-step explanation:

Here we can see that EF is a straight line ,

So we know that a straight line's value is 180°

Now ATQ ,

x+3+x+20+x+7=180°

or 3x+30=180

or 3x=150

or x=50°

Now value of X's are :-

i ) x+3 = 50+3 = 53°

i ) x+3 = 50+3 = 53°ii) x+20 = 50+20= 70°

i ) x+3 = 50+3 = 53°ii) x+20 = 50+20= 70°iii)x+7=50+7=57°
