Theorem: In any circles the same ratio of arc length to radius determines a unique central angle that the arcs subtend;
and conversely, equal central angles determine the same ratio of arc length to radius.
Prove the theorem above using the definition of the radian measure of an angle.

i think that you should ask google for the answer to that problem because if we don't know it google does

7.25

step-by-step explanation:

we know that 7 equals to 7.0. we also know that 1/4=0.25. so we can add the two together and we get 7.25

he earned 78.75 in interest.

step-by-step explanation:

answer: no

step-by-step explanation: because the big angle will spread away the 2 side that it is on and make the opposite side even longer.
