ind the measure of each angle in triangle ABC. Triangle A B C. Angle A is (8 x + 3) degrees, angle B is (7 x) degrees, angle C is (7 x + 1) degrees. 7x + (7x + 1) + (8x + 3) = 180 What is the value of x? x = What is the measure of angle A? m∠A = ° What is the measure of angle B? m∠B = ° What is the measure of angle C? m∠C = °

The table below represents the displacement of a fish from its reef as a function of time: time (hours) x displacement from reef (feet) y 0 4 1 64 2 124 3 184 4 244 part a: what is the y-intercept of the function, and what does this tell you about the fish? (4 points) part b: calculate the average rate of change of the function represented by the table between x = 1 to x = 3 hours, and tell what the average rate represents. (4 points) part c: what would be the domain of the function if the fish continued to swim at this rate until it traveled 724 feet from the reef? (2 points)
