Question statement

Using the right-angled triangle pictured below (not to scale), find the specified side lengths or angles using trigonometry and the given values.

Give your answers to two decimal places.

Before starting, check that your calculator is in degrees mode by verifying that $\cos{60} = \frac{1}{2}$ .

(If your calculator does not give this answer, press SHIFT $\rightarrow$ SETUP $\rightarrow$ 3 to enter degrees mode if using a Casio $fx$ model calculator, otherwise refer to your calculator's manual.)

You may find drawing a fresh diagram for each question helpful.

Give any introductory information the student needs.

			Name	Type	Generated Value

a	list	[ 7, 6, 9, 10, 3, 3, 4 ]
x	list	[ 40, 30, 60, 25, 50, 70 ]
fa	integer	5
fh	integer	10
fa_1	integer	3
