Question

A lighthouse is located on an island 300 feet from the shore of the mainland as shown. If x = 0.75 rad, what is d?

Answer 1

Answer:

d=382

Step-by-step explanation:

Work Shown:

d = 350*sec(x)

d = 350*(1/cos(x))

d = 350*(1/cos(0.41))

d = 381.62910632113

d = 382

Make sure your calculator is in radian mode.
