I agree with the other persons answer.
Answer:
Convert 33% to the equivalent decimal 0.33, and then multiply 0.33 by 67 to get 22.11.
Step-by-step explanation:
I'd suggest you write:
":<span>What is cos theta IF tan theta= 8/5?
tan theta = opp / adj = 8 / 5, so we know that opp = 8 and adj = 5. Then the length of the hypotenuse is sqrt(8^2+5^2) = 9.43.
Thus, the cosine of theta / cosine of this angle is
adj 5
----- = ---------- , or about 0.53.
hyp 9.43</span>
