The answer is C. I got this by doing a^2 + b^2= c^2. 50^2 + 16^2=c^2, 2500 + 256 = c^2, 2756 = c^2, then you take the square root of 2756 and that gives you your answer 52.50 yards. Hope this helps :D
6.
6 tons= 12,000 pounds
12,000-7,860= 4,140
so the answer is 4,140 pounds
7. 3 cups= 24 fluid ounces
40 - 24 = 16 fluid ounces
16 fluid ounces= 1 pint
so the answer is 1 pint left in the pitcher
8. 2.5 x 18= 45 feet
45 feet= 15 yards
so the answer is 15 yards
Correct. In the case where you are given enough information to use the law of cosines you could in fact then use the law of sines afterwards to find your remaining angle. That being said beware of solutions that don't make a feasible triangle (if you were using the law of cosines you only have one angle, so that means whatever your second angle is that you found using the law of sines can't make your sum go over 180, because you still need some angle left for the last angle).
