$\frac{32}{128} = \frac{x}{100} \\ x = \frac{32 \times 100}{128} \\ x = 25$
15.
$\frac{3}{36} = \frac{x}{100} \\ x = 8.3$
16.
$\frac{30}{100} = \frac{23.7}{x} \\ x = \frac{23.7 \times 100}{30} \\ x = 79$
17.
$\frac{7.5}{100} = \frac{12}{x} \\ x = \frac{12 \times 100}{7.5} \\ x = 160$

The sides of an equilateral triangle are 8 units long. What is the length of the altitude of the triangle?

beks73 [17]

Answer:

Option B.

Step-by-step explanation:

It is given that the sides of an equilateral triangle are 8 units long.

Draw an altitude of the triangle.

Altitude of an equilateral triangle is perpendicular bisector.

Let x be the length of the altitude of the triangle.

According to the Pythagoras theorem

$hypotenuse^2=base^2+perpendicular^2$

Using Pythagoras theorem we get

$8^2=4^2+x^2$

$64=16+x^2$

$64-16=x^2$

$48=x^2$

Taking square root on both sides.

$\sqrt{48}=x$

$4\sqrt{3}=x$

The length of the altitude of the triangle is 4√3 units.

Therefore, the correct option is B.
