The sum of m(angle)V and m(angle)W is 90 degrees. If sin W = 4sqarerootof2 divided by 7, what is cos V
~~~~~~~~~~~~~~~~~~~~~~

V and W are complement angles, since they are two acute angles in the right-angled triangle.

Therefore, W = 90° -V.

It implies

cos(V) = sin(90°-V) = sin(W) = %284%2Asqrt%282%29%29%2F7.
