The pythagorean Theorem

a^2 + b^2 = c^2

so

b^2 = c^2 - a^2

b^2 = 75^2 - 18^2

b^2 = 5625 - 324

b^2 = 5301

b = 72.8

Answer

72.8

72.8 is the answer

a^2+ b^2= c^2

18^2+ b^2 = 75^2

18 times 18 = 324

75 times 75 = 5625

324 - 5625 = 5301

Then find the sqrt root of 5301 which is 72.8

Hope this helps :)
