The height of the equilateral triangle below is 15 units. What is the value of x?

aleksley [76]

Step-by-step explanation:

The height of the equilateral triangle below is 15 units

Let x is the side of the equilateral triangle

Equilateral triangle is divided into to two special right triangles 30-60-90 degree triangles

Height is 15 units

Hypotenuse is x

use the general ratio of 30-60-90

compare the sides and find out hypotenuse x

$a\sqrt{3} =15\\\\\frac{a\sqrt{3}}{\sqrt{3} } =\frac{15}{\sqrt{3} } \\a=\frac{15}{\sqrt{3} }$

now replace the value of 'a' for x=2a

$x=2a\\x=2 \cdot \frac{15}{\sqrt{3} } \\x=2 \cdot \frac{15\sqrt{3}}{3} \\\\x= 10\sqrt{3}$

Answer:

$x= 10\sqrt{3}$

What’s the answer?? need help

Andre45 [30]

Answer:

option A

$\frac{(x+2)(x+5)}{x^{3}-9x }$

Step-by-step explanation:

Take LCM

$\frac{2x+5}{x(x-3)}-\frac{3x+5}{x(x^{2}-9)}+\frac{x+1}{(x+3)(x-3)}$

$\frac{2x+5}{x(x-3)}-\frac{3x+5}{x((x+3)(x-3))}+\frac{x+1}{(x+3)(x-3)}$

$\frac{(2x+5)(x+3)}{x(x+3)(x-3)}-\frac{3x+5}{x((x+3)(x-3))}+\frac{(x+1)(x)}{x(x+3)(x-3)}$

Now the Denominator is same we can add the numerator

$\frac{(2x^{2}+11x+15)}{x(x+3)(x-3)}-\frac{3x+5}{x((x+3)(x-3))}+\frac{(x^{2}+x)}{x(x+3)(x-3)}$

$\frac{2x^{2}-x^{2}+11x-3x-x+15-5}{x(x+3)(x-3)}$

$\frac{x^{2}+7x+10}{x(x+3)(x-3)}$

$\frac{(x+2)(x+5)}{x(x+3)(x-3)}$

$\frac{(x+2)(x+5)}{x^{3}-9x}$
