Find the value of x. then the measure of each angle

Asailor is looking at a kite. if he is looking at the kite at an angle of elevation of 36and the distance from the boat to the point where the kite is directly overhead is 40 feet, how high is the kite?

Two angles are complementary. the larger angle is 36 more than the smaller angle. what is the measure of the larger angle?

Solve each quadratic equation by factoring and using the zero product property. n^2 - 49 = 0
