That is called supplementary angles, so they add up to 180 degrees
So it would be 57 + x + 23 = 180
Add 57 and 23, which is 80, subtract that from 180, and you would get
x = 100
There are 1728 cubic inches in one cubic foot.
A cubic foot is 12"
12* 12" * 12" = 1728 cu/inches
therefore
1344/1728 =. 78 cu ft
Answer:
This is what I am learning in math rn so I'm not totally sure if this is correct but I'll try. I believe the answer is B.
Sorry, the way this is written is a little confusing, but I’m assuming you mean the equation is x^2 + 18x + 12? Sorry if I’m mistaken. If this happens to be the case, then the a value would be 1, the b value would be 18, and the c value would be 12. Again I’m assuming this is in the ax^2 + bx + c formula. I hope this helps, sorry if I’m wrong :/
