Find the Hypotenuse AC in Right Triangle with Legs 8 and 3

To solve for the length of side AC of triangle ABC, we will use the Pythagorean theorem as follows:

• Step 1: Identify the sides - Side AB is 8 units and side BC is 3 units.
• Step 2: Apply the Pythagorean theorem - $a^2 + b^2 = c^2$ where $c$ is the hypotenuse.
• Step 3: Substitute the lengths into the formula - $3^2 + 8^2 = AC^2$.
• Step 4: Calculate - $9 + 64 = AC^2$.
• Step 5: Simplify - $73 = AC^2$.
• Step 6: Solve for AC - $AC = \sqrt{73}$.

Therefore, the length of side AC in triangle ABC is $\sqrt{73}$.
