Answer:
17 units
Step-by-step explanation:
The sides of all right triangles share the same relationship known as the Pythagorean Theorem a² + b² = c². Substitute the lengths of the triangle into the theorem and solve for the unknown side. Since the problem does have an attached a picture, assume that a = 8, b = 15, and c = x.
8² + 15² = x²
64 + 225 = x²
289 = x²
√289 = √x²
17 = x
