a cliff is 125ft high. the angle of depression of a ship from the top of the cliff is 14.6 degrees. determine the distance of the ship from the foot of the cliff.

so the angle to the right of the 90 is 14.6 and the side opp. that is 125ft. how do i find the x. wat function would i use.? tan doesnt work as i thought it would.

sure it does

tan 14.6 = 125/x

x = 125/tan14.6
