Use pythagorean's theorem to solve for missing sides of a right triangle.
a^2 + b^2 = c^2
a = 11
b = 17
c = We don't know yet so I'll call it x
11^2 + 17^2 = c^2
121 + 289 = c^2
410 = c^2
c = √410
c = 20.2
Thus, the answer is B.
Hope this helps, and May the Force Be With You!

Answer:b.y=5x
this is the answer to your question
16 cm - 2.5 cm = 13.5 cm, which is 1/4 of the diameter of the large gear. Take 13.5 cm * 4, and you have the diameter of the large gear, which is 54 cm.
F(x)=y=2x+3
P (1,5)
Substitute x and y:
5=2*(1)+3
5=5 true
Point P (1,5) is on the graph of f.
