trasher [3.6K]

Answer:

The height of the tent = 3 feet

Step-by-step explanation:

Syrus is buying a tent with the dimensions shown below. The volume inside the tent is 36 feet^3. Syrus isn't sure if the tent will be tall enough for him to sit up inside. The tent is the shape of triangular prism whose length is 6 feet and width is 4 feet. What is the height of the tent?

Given:

Length of the tent = 6 feet

Width of the tent = 4 feet

Volume of the tent = 36

Solution:

Since the ten is in shape of triangular prism, so the volume of traingular prism is given as:

where  represents length,  represents width and  represents height of the prism.

Plugging in the know values of the dimension of the tent and the volume to find the height of the tent.

Simplifying.

\frac{36}{12}=\frac{12h}{12}

3=h

∴ h=3

Thus, the height of the tent = 3 feet

Answer:

e°=100°

Step-by-step explanation:

Sum of angles in a triangle= 180°

70°+30°+x°=180°

100°+x=180

Collect like terms

x°=180-100

x°=80°

e° is an exterior angle

exterior angle =180- interior angle

180°- x°

180°- 80°

=100°

e°=100°
