Since we know that the measure of one of the angles is 90°, we know that we have a right triangle with legs 1 and 
. Now lets apply the Pythagorean theorem: 
, to find our hypotenuse:
Now that we know that the measure of the hypotenuse is 2, lets use the trig function sine to find one of the angles that we are going to call
.
Remember that
, so:
Now that we have two angles, remember that the sum of the interior angles of a triangle is 180°; lets use that to find our final angle
:
We can conclude that the measure of the hypotenuse of our triangle is 2, and the measure of its missing angles are 30° and 60° respectively.
