Given:

LMN is an equilateral triangle.

LM = LN = MN = 12 cm

To find:

The height of the triangle h.

Solution:

In a right angle triangle,

\sin \theta=\dfrac{Opposite}{Hypotenuse}

\sin (60^\circ)=\dfrac{h}{12}

\dfrac{\sqrt{3}}{2}=\dfrac{h}{12}

Multiply both sides by 12.

\dfrac{\sqrt{3}}{2}\times 12=\dfrac{h}{12}\times 12

6\sqrt{3}=h

Therefore, the height of the triangle is 6\sqrt{3} cm.

a store advertises that customers can take 25% off the original price and ten take an extra 10% off. is this the same as a 35% o
maksim [4K]

Answer:

No, they are not the same.

Step-by-step explanation:

Lets say the price is 100 dollars. Lets start with the 25 and then 10 percent off. Since its 25% off we need to multiple the 100 dollar price by .75.

100*.75=75

Now that we have the 75 dollar price, we need to take off the 10%. We need to multiply the current price of 75 by .9

75*.9=67.5

The price after these 2 discounts is $67.50

Now lets do the 35% off right away. Since is 35% off we need to multiple our right of 100 by .65.

100*.65=65

The price after the 35% off is $65

So no, they are not the same.
