An equilateral ∆ has sides of length 16 cm. Find the length of an altitude.

inn [45]

The length of the altitude is $8\sqrt{3}$

Explanation:

Let ABC be an equilateral triangle.

It has sides of length 16 cm

Let AD be the altitude of the triangle.

We need to determine the length of an altitude.

Let AC = 16 cm and CD = 8 cm

Let us consider the right angled triangle ADC

Using the Pythagorean theorem, we have,

$AC^2=AD^2+DC^2$

Substituting the values, we get,

$16^2=AD^2+8^2$

$256=AD^2+64$

$192=AD^2$

$8\sqrt{3}=AD$

The length of the altitude is $8\sqrt{3}$

What is a good estimate for 470% of 40? Explain.

Harlamova29_29 [7]

Answer:

470% is equivalent to the decimal 4.7, which can be rounded to 5

So, 470% of 40 is approximately equal to 5 times 40

which is equal to 200

So, a good estimate for 470% of 40 is 200.
