Answer:
x = 65
y = 65
Explanation:
This is a special right triangle with angle measures as follows:
90° - 45° - 45°
The side lengths are represented respectively as follows:
a√2 - a - a
The side length that sees angle measure 90°, hypotenus, is given as 65√2.
The legs are congruent because this is a isosceles triangle at the same time so each = 65.
