Answer:
5 units
Step-by-step explanation:
we can identify this as an isosceles triangle because both angles are equal (= 45 deg). Hence we can also conclude that the vertical leg of the triangle must also be "s"
We an also identify this as a right triangle because we have one angle that is 90 degrees. Hence we can use the Pythagorean formula to solve this (see attached for reference)
(5√2 )² = S² + S²
(5)²(√2 )² = 2S²
(25)(2) = 2S²
25 = S²
S = √25
S = 5 units
