b. 1/15^-2
c. 15^4
d. 15^-4

The answer would be A)

Step-by-step explanation:

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2
