Answer the attached question.

What are the measures of ∠a, ∠b, ∠c and ∠d? explain how to find each of the angles. measure need asap

The height of a flare fired from the deck of a ship in distress can be modeled by h(t)= -2(8t^2-52t-28), where h is the height of the flare above water and t is the time in seconds. a. find the time it takes the flare to hit the water.

Use composition to determine if (x) or h(x) is the inverse of f(x) for the limited domain x2-1.
