Congruent triangles are exactly the same, meaning they have the same side length, and thus same angles. Everything is exactly the same, as easy as it gets :)
So, you can compare the two pictures to get the informations you need:
, since it is a right angle
, as we can see on the right by comparison
. In fact, the angles of a triangle sum to
, so we have
. So,
yd, as we can see on the left by comparison.
Finally, we can compute using the Pythagorean theorem:
