27Find the angle coterminal with 17m3 28 A ladder 5 m long l

27·Find the angle co-terminal with 17m/3 28. A ladder 5 m long, leaning against a vertical wall makes an angle of 65 with the ground. a) How high on the wall does the ladder reach? b) How far is the foot of the ladder from the wall?

Solution

27. 17pi/3

coterminal angle=17pi/3 -4pi =5pi/3

So the angle coterminal with 17pi/3 is 5pi/3. .
