Answer:
All I know for a fact is that number 10 is C
Step-by-step explanation:
Answer:
x =76.45 degrees
Step-by-step explanation:
72 + 252 – 2(7)(25)cos _x__=242
combine like terms
324-350cosx = 242
subtract 324 from each side
-350x = -82
divide by -350
cos x = -82/-350
cos x = 82/350
take the arccos of each side
arccos (cos x) = arccos (82/350)
x =76.45 degrees
If you times it the answer is going to be 1,200
the least common multiple of 8 and 6 is 24
