Pre-Calculus HW WS 5-3 Name: _______________________ Hour: _______

When a ladder is rested against a tree, the foot of the ladder is 1 m from the base of the tree and forms an angle of 64˚ with the ground. How far up the tree does the ladder reach, to the nearest tenth of a meter? Kendra walked diagonally across a rectangular field that is 45 m by 65 m. To the nearest degree, at what angle with respect to the longer side did she walk? Find all trig ratios of theta at the right. ∆ABC is an isosceles triangle with equal sides of 5 cm. The base of the triangle is 8 cm. Find all three angles of the triangle to the nearest degree. If you were in a hot air balloon 500 m over Kelowna, BC, at what angle of depression would you look at a point on the ground 800 m horizontally from the balloon?
