Answer:

Step-by-step explanation:
The triangle is a right triangle.
We can use trigonometric functions to solve the problem.
tan θ = opp/adj
tan 30 = y/(4√3)
y = 4√3 tan 30
y = 4
It’s going to be the area of the triangle on the side times the length, so 0.5 x 36 x 15 x 48 = 12960
B and d should be the answer
