I need help i dont know what i did wrong
I given the short leg measure as 10 so that means the hypotenuse should be 20. I need to figure out the long leg.
a^2 + b^2 = C^2
a^2 + 10^2 = 20^2
a^2 + 100 = 400
a^2= 400 - 100
a^2 = 300
a = sqroot of 300
I given 4 possible answers. I dont see how any of them are right
