For this, you'll need to use the pythagorean theorem
Do you know what that is?

Let's first draw it out

snowflake0531 · Answer

The pythagorean theorem is
$$a^2 + b^2 = c^2$$
where c is the hypotenuse, and a and b are both the legs

dizzymustang156 · Answer

he has the answer tho but
u can do it

snowflake0531 · Answer

By using this we get
$$20^2 + b^2 = 25^2$$
SImplifying that we get
$$400+b^2 = 625$$
and we isolate the b^2
$$b^2 = 225$$
Which is, 15
