Answer:
x = 37
y = 6
Explanation:
(i may be incorrect) The two triangles within the whole are congruent. So, the given angle will be the same on the other triangle. Since we know this, we can assume that there are two right angles.
180 - 90 - 53 = x
180 - 90 - 53 = 37
(y is basically given as 6, considering the congruent sides)
