If the hypotenuse of a right triangle is 6m and one side is 4m, what is the length of the other side?

Use the Pythagorean Theorem: a^2 + b^2 = c^2 
a and b are the measures of the legs and c is the measure of the hypotenuse 

Let's solve for a (the length of the other leg) 
*I am hoping that m is not a variable and just an abbreviation for meters* 
b = 4 m 
c = 6 m

a^2 + 4^2 = 6^2
a^2 + 16 = 36
a^2 = 20
a = 
after simplifying...
a =  m 

If gravity is one third on mars then weight also one third on mars
