Answer:
Option A, x = [tex]\sqrt{80}[/tex]
Step-by-step explanation:
Pythagorean Theorem states: A² + B² = C² ( A and B are the legs, C is always the hypotenuse)
⇒ A² + B² = C²
⇒ 4² + 8² = x²
⇒ 16 + 64 = x²
⇒ 80 = x²
⇒ [tex]\sqrt{80} = \sqrt{x^{2} }[/tex]
⇒ [tex]\sqrt{80} = x[/tex]
Hope this helps!
