15 units
Step-by-step explanation:
I just took this geometry test with the same question. Its 15
X/7= -3
X= -21
Hope this helps!
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
