Question

Help ASAP! Can someone explain how?

Answer 1

Answer:

Step-by-step explanation:

cos theta is 5/13

so, adjacent=5 ,hypotenuse=13 and opposite=?

hypotenuse^2=adjacent^2+opposite^2

13^2=5^2+opposite^2

169-25=opposite^2

$\sqrt{144}$=opposite

12=opposite

sin theta=opposite/hypotenuse

=12/13
