13. Oscar's dog house is shaped like a tent. The slanted sides are both 5 feet
VashaNatasha [74]

Answer:

The height of the dog house = 4 feet.

Step-by-step explanation:

Given:

The shape of the dog house is like a tent.

The slant heights of the house is 5 feet.

The bottom of the house is 6 feet across.

To find the height of the dog house at its tallest point.

Solution:

On drawing the figure of the dog house in the shape of a tent, we find out that the tallest point would be at the midpoint of the bottom of the house.

Thus, we ave a right triangle, of which one leg = \frac{6\ ft}{2}=3\ ft and hypotenuse = 5\ ft

<em>Applying Pythagorean theorem to find the measure of the other leg which is the height of the house.</em>

Hypotenuse^2=Leg1^2+Leg2^2

Plugging in values.

5^2=3^2+Leg2^2

25=9+Leg2^2

Subtracting both sides by 9.

25-9=9-9+Leg2^2

16=Leg2^2

Taking square root both sides.

\sqrt{16}=\sqrt{Leg2^2}

4=Leg2

Thus, the height of the dog house = 4 feet.

Answer: 8/3

Step-by-step explanation:

So first what you do is you have to add the whole number to the numerator and you do that by multiplying the whole number by the deniminator which is 6. Now you add the 6 to the numerator which is 8, so you get 8/3.

Sorry this got so complicated. Hope this helped!
