Answer 2

So what do you need help with in the problem?

Answer 3

Do you know how to do this?

Answer 4

C=cos^-1(22^2+24^2-26^2/2(22)(24)) C=68.68 Degrees I just wanna like make sure I aam doing the steps right to solve for the angle

Answer 5

to find A would we use the same equation?

Answer 6

except you would subtract a^2?
