Answer:
b
Step-by-step explanation:
I think that the answer should be c but i am not sure <span />
It takes 16 cups of water to make a gallon
Im assuming it would be 60 or 60.375(Work below)
Because usually when it says "out of" it means divide so i divided 8 from 21 and got 2.625 so then i took the 63 and subtracted 2.625 from that and got 60.375 so its either 60 or 60.375 again im not sure if im wrong im very sorry.
When you bisect something you are cutting it in half. so in the image above when you cut it in half you would be forming 2 angles. Your answer is D. because when you cut in half you are going to have equal sides. Its like taking an 75 degrees and bisecting it and each of the new angles would be 37.5.
