Answer:
x = 3
Step-by-step explanation:
Hi there!
<u>1) Prove similarity</u>
The two triangles are similar due to angle-angle similarity. They both have an angle measured 90 degrees and the angles of the two corners that touch are equal, because opposite angles are equal.
<u>2) Solve for x</u>
Now, we can set up a proportion to solve for x:

Therefore, x is 3 units long.
I hope this helps!
