Answer:
x=16
Step-by-step explanation:
First, since a and b are parallel, infer that 4x and 60 can be added together to reach 124 (4x+60=124). Then, solve the equation.
4x+60=124
subtract 60 from both sides
4x=64
divide by four
correct ans is option/graph Dbecoz 36/3 = 12
144
I have made it in above figure so each angle will 150 degree
