Use the law of sines....(sina/A=sinb/B=sinc/C for any triangle)
What that means is the sine of an angle divided by the length of the side opposite the angle is a ratio that is true each angle/side pair...In this case:
sin90/122=sinc/22 rearrange to solve for sinc
sinc=(22sin90)/122 now take the arcsin to solve for c
c=arcsin[(22sin90)/122]
c≈10.388857815469611987441020361405
c≈10.39° (to nearest hundredth of a degree)

Answer:
u didn't show anything so I can't help u. can u show a picture or something
Cos = adj/hyp
hyp = AB
cos(25) = 7/AB
AB = 7.7
