#1**+3 **

Best Answer

The Pythagorean theorem says that:

**(leg) ^{2} + (other leg)^{2} = (hypotenuse)^{2}**

One leg is **15**.

The other leg is the **missing side**.

The hypotenuse is **17**.

All you have to do is plug in the right numbers into the right slots.

Can you get that far with it?

#2**+1 **

Use the Pythagorean theorem:

a^{2}+b^{2}=c^{2}

a^{2}+15^{2}=17^{2}

a^{2}+225=289

a^{2}=289-225

a^{2}=74

a=sqrt(74)
