Answer 1

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:

$x = 90^\circ$, since it is a right angle

$y = 38^\circ$, as we can see on the right by comparison

$w = 52^\circ$. In fact, the angles of a triangle sum to $180^\circ$, so we have $x+y+w = 90+38+w = 128+w = 180$. So, $w = 180-128 = 52$

$v = 7.9$yd, as we can see on the left by comparison.

Finally, we can compute $z$ using the Pythagorean theorem:

$z = \sqrt{u^2+v^2} = \sqrt(6.2^2+7.9^2) \approx 10$

Answer 2

approxamitly 10 is the answer
