Aleg of a triangle is 2 units and the hypotenuse is 4 units, what's the length of the other leg of the triangle?
a. 2 units
b. 6 units
c. 12 squared
d. 20 squared

The equation that you would use would be 4^2-2^2=a^2 (a^2+b^2=c^2). you would have to square the numbers and subtract. then your answer should be the square root of 12. So the answer technically would be C, but it worded kinda weird. It should say "the square root of 12". Hope this helped.
