II Solve the ff. problems using trigonometric or inverse trigonometric functions Show lillustration, define variables used and give a detailed solutions. 1. A statue 10 feet high is standing on a base 13 feet high. If an observer's eye is 5 feet above the ground, how far should he stand from the base in order that the angle between his lines of sight to the top and bottom of the statue is a maximum. (How far should he stand to get the best view of the statue. 2. A steel girder 27 feet long is to be moved on rollers along a passageway 8 feet in width and into a corridor at right angles to the passageway. it the horizontal width of the girder is neglected, how wide must the corridor be in order that the girder can go around the comer?
