Right Triangle Trig TS Making Decisions After Reflection

Right Triangle Trig TS: Making Decisions After Reflection & Review Warm Up: 1) Find t in radians (0 < t < π/2). Don’t use a calc! That’s cheating!!! 2) a) csc t = b) sin t = 3) 2) Solve for x. Don’t round ever!!! x 10 45° 70° 15

Given A = 21° and a = 15, solve the right triangle. B C A

Given sinθ = ¼ find all five other trig functions for θ given θ is acute.

Given csc t = 3 and sec t = Find… a) cos t b) cot t c) cos (π/2 – t) *a thinker problem…hmm what is special about that angle…

Let’s see what ya got! On the next slide there is a multi-step word problem using right triangle trig. You will need your calculator. However, you must either not get your answer until the very end, or you should use the “store” feature on your calculator to get an answer WITHOUT rounding error. Meaning your answer must be precisely the same as mine.

Sadly you are leaving Banff, Canada and the lovely Canadian Rockies behind. You stop at two different scenic viewpoints. At the first viewpoint you have to tilt your binoculars to an angle of elevation of 9° to look back longingly at the snow capped peak. After narrowly avoiding a moose you complete the 13 mi drive to the second view point where you only have to tilt your binoculars 3. 5° to see the same peak. Exactly how tall is the mountain? Ans: The ever so marvelous mountain is approximately 1. 295 mi in height 3. 5° 13 mi Very majestic mountain… 9°
