Trig Values of the Special Right Triangles Worksheet with Answer Key

What's on the worksheet

1. Evaluate each trig expression exactly, with denominators rationalized:
   2\cos 30^\circ \tan 30^\circ\sin 45^\circ \cos 45^\circ\tan^2 60^\circ - 1\dfrac{\cos 45^\circ}{\sin 30^\circ}1 - 2\sin^2 30^\circ
2. Solve each equation for the acute angle in degrees:
   2\sin\theta - 1 = 0\sqrt{3}\tan\theta = 34\cos^2\theta = 22\cos\theta = \sqrt{3}4\sin^2\theta - 3 = 0
3. Put five trig values in order from least to greatest without a calculator.
4. Find the side and angle of a rectangle with a diagonal of 12 and a side of 6.
5. Evaluate each expression exactly and say which table value it equals.
6. Find the height and floor reach of a 14 m conveyor belt at 30 degrees.
7. Find what is wrong with Ava's redrawn 30-60-90 triangle and fix her values.
