Question

Is anyone really good at math?

Answer 1

Answer: 12 cm

Step-by-step explanation:

$\mathtt{Using\ the \ pythagorean \ theorem: \\}$

$a^2+b^2=c^2, \\\ we\ can\ plug\ in\ values\ for\ a,\ b,\ and\ c$

$L=a\ and\ M=b\ and\ N=c$

Therefore,

$L^2+35^2=37^2\\L^2+1225=1369\\L^2=144\\\sqrt{L^2} =\sqrt{144} \\L=\pm12\\Taking\ only\ the\ positive\ answer,\ we\ get:\\\large\boxed{L = 12cm}$

Answer 2

We have: L² + M² = N²

=> L² = N² - M² = 37² - 35² = 144 = 12²

=> L = 12
