The triangle below is equilateral. Find the length of side xx to the nearest tenth.
x
6
The length of side xx can be found by using the Pythagorean Theorem. Since the triangle is equilateral, all three sides are equal. Let's call the length of side xx a.
Using the Pythagorean Theorem:
a^2 + 3^2 = 6^2
a^2 + 9 = 36
a^2 = 27
a = √27 ≈ 5.2
Therefore, the length of side xx is approximately 5.2 units.
