Do the pythagoream theorm.
Do you know what the pythagoream theorm is?

Answer 5

not exactly

Answer 6

So is line segment ZY one of the leg, or a hypotenuse?

Answer 7

hypotenuse

Answer 8

no just a leg

Answer 9

Great. It's the leg.
So you can use the pythagoream theorm: \[\large \large a^2 + b^2 = c^2\]
The variable c always represent the hypotenuse, while a, and b, represent the legs.
