If its on a graph just look for the spot where the line meets the y and x-axis
Which graph? Please explain in the comments
The triangle is isosceles so m∠A and m∠C are the same.
So to find ∠B, we do 74 + 74 + b = 180
148 + b = 180
b = 180 - 148
b = 32
Answer B is the right choice.
N=1/100 this is the answer
i thank it is B i hope that helped
