Tutorial Exercise Complete the equation. arcsin /25 - X2 = arccos ( ), OSXS 5 5 Step 1 Consider a right triangle with an acute angle u. If u = arcsin 25 - X2 then V 25 -x2 = sin u sin u 5 5 Step 2 Using sin u = V 25 - X2 obtain the opposite side and hypotenuse of a right triangle with acute angle u. 5 opp = V 25 - x2 hyp = Use the Pythagorean Theorem to find the adjacent side of angle u.
