1) Snoopy leans an \(8\) foot ladder against a fence that is perpendicular to the ground. He asks Woodstock to stand at the bottom of the ladder to keep it steady. The bottom of the ladder is \(3\) feet from the fence. Find the angle of elevation from Woodstock at the bottom of the ladder to Snoopy at the top to the nearest tenth of a degree?
2) Find the angles of a right triangle with legs of lengths \(9\) and \(40\). What are the angle measures to the nearest tenth of a degree.
3) An isosceles triangle has a base of \(12\) ft and legs that are \(20\) ft. Find the measure of a base angle to the nearest tenth of a degree.
4) An observer is \(150\) meters from the base of a glacier that is \(0.9\) km high. To the nearest tenth of a degree, what is the angle of elevation from the observer to the top of the glacier?

6) A wheelchair ramp design of \(40\) feet at the entrance point on ground that inclines. The ground measures \(39.5\) feet and the angle of the ground with vertical is \(92.2^{\circ}\). According to the ADA guidelines, a handicap ramp must not exceed an angle of elevation above \(4.8^{\circ}\). What angle does the ramp make? Does the ramp meet ADA guidelines?
7) A plane approaching Chicago O’Hare is \(11\) miles away and flying at an altitude of \(3000\) feet. What is the angle of depression, to the nearest tenth of a degree, from the airplane to the airport?
