1. Problem Description

The problem asks to find the height hh of an equilateral triangle, given that the base of the triangle is
1
0.

2. Solution Steps

Since the triangle is equilateral, all sides are equal in length. The height bisects the base, creating two right triangles. The base of each right triangle is half of the base of the equilateral triangle, which is 10/2=510/2 = 5. The hypotenuse of each right triangle is the side length of the equilateral triangle, which is
1

0. We can use the Pythagorean theorem to find the height $h$.

a2+b2=c2a^2 + b^2 = c^2
where aa and bb are the legs of the right triangle and cc is the hypotenuse.
In this case, a=5a = 5, b=hb = h, and c=10c = 10.
52+h2=1025^2 + h^2 = 10^2
25+h2=10025 + h^2 = 100
h2=10025h^2 = 100 - 25
h2=75h^2 = 75
h=75h = \sqrt{75}
h=25×3h = \sqrt{25 \times 3}
h=25×3h = \sqrt{25} \times \sqrt{3}
h=53h = 5\sqrt{3}

3. Final Answer

h=53h = 5\sqrt{3}
