Hello! I need some help on this please, The question is provided below in the picture! If you do figure out the answers could you number them? And Etc, Thank You So so much! Correct answers definitely get brainiest, Do not answer absurd answers, please

the correct answer is:

definition of sine in right triangle

explanation:

the ratio for sine is opposite/hypotenuse. this means that for the sine of angle b, we want the side opposite b, which is ae, over the hypotenuse, which is c:

sin b = ae/c

multiply both sides by c:

c sin b = (ae/c)*c

c sin b = ae

this is by definition of sine.

this also applies to step 8.
