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.
You combine both 2x-12 and x+2 and 11 which makes the equation
2x-12+x+2= 11
The you get your answer which is
X=7
If you add a zero at the end it is easier to understand. 0.20 > 0.18 because 20 is greater than 18
A= 20 cause 5-2=3 and if the top is 23 it has to be 20
