△abc is a right triangle with right angle at ∠b .
ab=42 cm
bc=34 cm

what is the measure of ∠a , to the nearest degree?

This is the correct answer, I have taken the test and am posting the answers in hopes of helping other people :]

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,

central angle of a triangle has the same measure as its intercepted arc.
