Question

what is the length of y in this picture? 90 45 5 5√2

Explanation:

Step1: Identify the triangle type

This is a 45 - 45 - 90 right - triangle. In a 45 - 45 - 90 triangle, the legs are equal.

Step2: Apply the property

Since one leg is 5, the other leg \(y\) is also 5 (because in a 45 - 45 - 90 triangle, \(a = b\) where \(a\) and \(b\) are the legs).

Answer:

5
