A lighthouse is sitting on a small island in the ocean. I measure the angle in the ocean. I measure the angle of elevation of the top of the lighthouse as 42.5 degrees. I walk 50 feet towards the lighthouse and now measure the angle of elevation as 51 degrees. Find the height of the lighthouse.

answer: b.48 for

step-by-step explanation:

shift 4 units up, and 1 unit left.

it will translate f(x) = 3^x to g(x) = 3^(x+1) + 4

11.2

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
