Question

find the length of side a to the nearest tenth.
answer

Explanation:

Step1: Use Pythagorean theorem

Let the two equal sides be \(a\). According to the Pythagorean theorem \(a^{2}+a^{2}=(\sqrt{8})^{2}\).

Step2: Simplify the equation

\(2a^{2}=8\), then \(a^{2} = 4\).

Step3: Solve for \(a\)

Take the square root of both sides, \(a=\sqrt{4}\), so \(a = 2\).

Answer:

\(2\)
