Hello!
To solve this, we will use the Pythagorean Theorem, where the hypotenuse is c, and the legs are a and b.
a²+b²=c²
As we can see, we already know the length of the hypotenuse, so we will switch the formula around to solve for a, the missing leg.
c²=b²=a²
Now we will square our numbers and subtract. Then we will find the square root of our answer to undo the exponent and find a.
64-25=39
√39≈6.24
The length of the other leg of the triangle is about 6.24 unites.
I hope this helps!
