Answer:4
Step-by-step explanation:
The formula we want to use for this is leg^2 + leg^2 = Hypotenuse^2
Let’s make x the other leg length since that’s what we are trying to find.
So it should look like this
Equation: 1.5^2 + x^2= 2.5^2
1) lets square them
2.25 + x^2 = 6.25
2) let’s get x^2 by itself so what we will do is subtract 2.25 from both sides
X^2 = 4
3) we need to remove the exponent from x so what we would do is put a radical on 4 and since we need to get four out of the radical, we need two of the same numbers that multiply to get four with is 2 because
2x2=4
4) so ur answer would be 2
X=2
