Given that the triangles are similar, find the lengths of the missing sides. 90 100 x y 10 8 Solution: There is one side missing in the triangle on the left. This side is labeled x. There is also one side missing from the triangle on the right. This side is labeled y. The side x in the triangle on the left

The opposite side is given to us: 2, but the hypotenuse is not. Since we have a right-angled triangle, we can use Pythagoras to find the hypotenuse. If the hypotenuse is c, then a and b are both 2, so the equation a^2+b^2=c^2 becomes: c^2=2^2+2^2=4+4=8 . Square rooting both sides, we get: c=\sqrt{8}=2\sqrt{2}
