Solution

Question number 6 and 7 are absolutely correct

8. cos theta= -10/13    and theta is in second quadrant

In second quadrant sine is positive

cos theta=adjacent /hypotenuse

adjacent=10 hypotenuse=13

opposite=sqrt(hypotenuse²-adjacent²)=sqrt(169-100)=sqrt69

sin theta=opposite/hypotenuse=sqrt69/ 13=.6390
