Let (in radians) be an acute angle in a right triangle and let and y, respectively, be the lengths of the sidesadjacent to and opposite . Suppose also that a and y vary with time.At a certain instant x = 9 units and is increasing at 1 unit/s, while y = 8 and is decreasing at units/s.How fast is changing at that instant?Answer:

Given adjacent side = x opposite side = y

Let (in radians) be an acute angle in a right triangle and let and y, respectively, be the lengths of the sides adjacent to and opposite 0. Suppose also that a and y vary with time. At a certain instant x = 9 units and is increasing at 1 unit/s, while y = 8 and is decreasing at How fast is changing at that instant? Answer: units/s.
