∠a is an acute angle in a right triangle. given that sina=725, what is the ratio for cosa?

The other person is correct, but it´s not 7/25, it´s the first one they put which is 24/25

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.

hope this ! have a great day.
