The velocity v (in meters per second) of an object that is thrown straight upward with an initial velocity v, is given by v = v. - 9.8t, where t represents time in seconds. If a ball is thrown upward at 30 meters per second, when will its velocity drop to 5 meters per second? Round to the nearest tenth of a second.​

step-by-step explanation:

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
