no that's wrong. So you have an angle and the hypotenuse length you can use the trig equation sin(angle) = opposite/hypotenuse -> opposite = hypotenuse*sin(angle)

sin(45) = .707 and the rest is just a plug and chug.

oh no dear it is not that hard

one angle is 45 degrees, so the other angle is also 45 degrees that means the triangle has two equal angles, so two equal sides

7. misty1212

the hypotenuse is $$5\sqrt 2$$ so the other two sides are the hypotenuse divided by $$\sqrt2$$ i.e. $\frac{5\sqrt2}{\sqrt2}=5$
