Answer:
x = y = 5
Explanation:
This triangle and its markings show that the acute angles are equal. Given that it is a right triangle, this is a 45-45-90 triangle. This also means that the values of x and y are equal. Note that for any triangle, if two angles are equal, then their corresponding side lengths are also equal. The side lengths for this type of triangle follow the pattern s - s - s√2 where the first two are side lengths and last value is the length of the hypotenuse. (s represents the length of a side)
We want to find x and y, so we need the value of s.
s√2 = 5√2
s = 5
Therefore, x = 5, y = 5.
