X = 13, assuming they are the same length.
Using the pythagorean Theorem formula (a^2 + b^2 + c^2) Plug in A and B (13, and 13).
(13)^2 + (13)^2 = c^2
13 • 13 + 13 • 13 = c^2
169 + 169 = c^2
v/338 = v/c^2 (square root them both)
Then you can have your answer for y, hope this helps

Maya is finding the area of the shaded triangle below.
Ahat [919]
The answer is 73 because it is the only number that is showing the measurement of the bottom of the triangle. Don't get confused with 22 they put the line of 10 after 22 to trick your brain up but reading the problem again they are asking for the WHOLE triangle.
