Three paths intersect to form a right triangle as shown here. The path from the picnic area to the fountain is 500 yards. The path from the fountain to the restrooms is 300 yards. How far are the restrooms from the picnic area?

400 yd

Step-by-step explanation:

It's a 3 - 4 - 5 triangle

If the hypotenuse is a multiple of 5 and another length is the same multiple of 3 or 4, the one left over will be the same multiple of the one that's left.

if you was gonna solve for a, a is a   < -12

just get this app called photo math it should be able to do those
