Question

1. Select an angle OTHER THAN the right angle in the diagram and WRITE that angle.

2. State whether you will apply the trig function sin, cos, OR tan.
3. List the RATIO (fraction) that is equivalent to the trig function (you chose in #2) applied to that angle you chose in #1

Answer 1

1) using angle Z

2) sin(Z) = opposite/hypotenuse

sin(Z) = 21/35 = 3/5

3) cos(X) = adjacent/hypotenuse

cos(X) = 21/35 = 3/5

Answer 2

see below

Explanation:

<X

Sin X = opp side/ hypotenuse

= 28/35

=4/5
