Answer:

x = √55

Step-by-step explanation:

using Pythagoras Theorem:

x² + 3² = 8²

x² = 64 - 9

x² = 55

x = √55 ..........this is your answer in radical form.

x = 7.416

Answer:

x = √55 = 7.4162

Step-by-step explanation:

The Pythagorean Theorem states that a^2 + b^2 = c^2

so 3^2 + x^2 = 8^2

x^2 = 64 - 9 = 55

x = √55 = 7.4162
