<span>If tan theta= 15/8, then theta is expected that theta is found in the first and third quadrant. the y-component is 15 and the x-component is 8. hence the hypotenuse is 17 from the pythagoren theorem. cos theta thus is equal to 8/17, sec theta is equal to 17/8. csc theta is equal to 17/15. answer are A and D</span>
Answer:
b
Step-by-step explanation:
The answer isn't A or B because those two are not factored. D is wrong because 8•8=64 not 16. So that leaves us with C (4•4=16).
