Given:
The figure of an equilateral triangle with side length 14 in.
To find:
The height x of the equilateral triangle.
Solution:
We know that the height of an equilateral triangle is:
![h=(√(3))/(2)a](https://img.qammunity.org/2022/formulas/mathematics/high-school/ju43389fr7e60qo44w8wwiqe6au187yj5p.png)
Where, a is the length of side of the equilateral triangle.
It is given that the height of the triangle is
.
Putting
in the above formula, we get
![x=(√(3))/(2)(14)](https://img.qammunity.org/2022/formulas/mathematics/high-school/q7ztpapylno6u8yr02aw7h8m5jv18g4t5t.png)
![x=√(3)(7)](https://img.qammunity.org/2022/formulas/mathematics/high-school/8cr9lyk76dxu8fygd5l0959bc3wkm6k4w6.png)
![x=7√(3)](https://img.qammunity.org/2022/formulas/mathematics/high-school/i5rlyijunw2dper0wo04sn5czlr6r2x57g.png)
Therefore, the height of the triangle is
.
