Question 1168789: suppose 0<Θ< pi/2 and tan =7/8. evaluate cos Θ and sin Θ.
Answer by htmentor(1343)   (Show Source):
You can put this solution on YOUR website! If the tangent is 7/8, that means that the altitude and base of the right
triangle are 7 and 8, respectively. Thus the hypotenuse is sqrt(49+64) = sqrt(113),
and the sin and cos, are 7/sqrt(113) and 8/sqrt(113), respectively.
