In this right triangle, you are given the measurements for the hypotenuse, c, and one leg, b. The hypotenuse is always opposite the right angle and it is always the longest side of the triangle. To find the length of leg a, substitute the known values into the Pythagorean Theorem. Solve for a2.

SOH- you know to use Sine when you are given the Opposite and Hypotenuse

CAH- you know to use Cosine when you are given the Adjacent and Hypotenuse

TOA- you know to use Tangent when you are given the Opposite and Adjacent

Hope this helps

$\bf f(x)=-2x^2+11x\implies \left. \cfrac{df}{dx}=-4x+11 \right|_{x=9}\implies -4(9)+11\implies -25$
