Triangle abc is a right triangle and sin(53o) = . solve for x and round to the nearest whole number.

which equation correctly uses the value of x to represent the cosine of angle a?

cos(53o) = 4/x

cos(53o) = y/5

cos(53o) = x/4

cos(53o) = 5/y

How do i do this activity, is appreciated

Use circumcenter theorem to solve for the given values

Gravel is being dumped from a conveyor belt at a rate of 25 ft3/min, and its coarseness is such that it forms a pile in the shape of a cone whose base diameter and height are always equal. how fast is the height of the pile increasing when the pile is 14 ft high? (round your answer to two decimal places.) ft/min
