AB = AC, so this is an isosceles triangle, then angle B=angle C =66⁰.
m∠BAD = m∠CAD, so AD is a bisector.
In an isosceles triangle, bisector is also median and height.
So AD is perpendicular bisector.
So angle x = 90⁰.
In triangle ABC
m∠A+m∠B+m∠C=180⁰
m∠A+66+66=180
m∠A=180-66-66=48⁰
m∠A=48⁰
AD is a bisector of A, so y=m∠A/2=48⁰/2=24⁰
x=90⁰, y=24⁰
Answer is A
You would want to make it into an addition problem that looks like this:
2x²+3x-4
+ x² - x - 2
___________
3x² + 2 - 6
26.25 divided by 3 is 8.75 so the answer is B, just divide the about of money by the number of hours and you have your answer
