Question

Find the value of x in the triangle shown below.

Answer 1

Answer:

Option A, x = $\sqrt{80}$

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

⇒ $\sqrt{80} = \sqrt{x^{2} }$

⇒ $\sqrt{80} = x$

Hope this helps!
