If the hypotenuse of a right triangle is 2sqrt 3 units long and one of the legs is sqrt3 units long, then how long is the other leg?

To find the answer, you need to know the formula of Pythagorean theorem which is:
a²+b²=c² where c represent hypotenuse, a represent one of the leg and b represent t another leg
In this case, we know that:
c=2√3
a=√3
b=?
Put all the variable an number into an equation which is
(√3)²+b²=(2√3)²
3+b²=12
Subtract 3 to each side
3+b²-3=12-3
b²=9 unit
Square root to each side
√b²=√9
b=3 unit long. As a result, the other leg is 3 units long. Hope it help!
