A woman looks out a window of a building. She is 94 feet above the ground. Her line of sight makes an angle of O with the building. The distance in feet of an object from the woman is modeled by the function d = 94 sec θ. How far are objects sighted at 25° and 55°?

They want you to plug in 25 to get some number out for d. Same for 55 keep in mind that sec(theta) = 1/cos(theta)

http://web2.0calc.com/#94*(1/cos(25)) when you get to that link, hit the "=" button to have the calculator compute the result
