Answer:

BC ≈ 8.9 units

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos36° = $\frac{adjacent}{hypotenuse}$ = $\frac{BC}{AB}$ = $\frac{BC}{11}$ ( multiply both sides by 11 )

11 × cos36° = BC , then

BC ≈ 8.9 ( to the nearest tenth )

At a campground, a rectangular fire pit is 7 feet by 6 feet. What is the area of the largest circular fire that can be made in t

Fittoniya [83]

The area of the circular fire pit is 4096 square inches.

Explanation:

Given that the rectangular fire pit is 7 feet by 6 feet.

We need to determine the area of the largest circular fire that can be made in this fire pit.

The diameter of the circular fire is 6 feet

The radius is given by

$r=\frac{6}{2} =3$

Radius is 3 feet.

The area of the largest circular fire pit can be determined using the formula,

$Area=\pi r^2$

Substituting the values in the formula, we have,

$Area = (3.14)(3)^2$

$=(3.14)(9)$

$Area= 28.26 \ ft^2$

We need to convert feet to inches by multiplying by 12, we get,

$Area = 28.26\times (12)^2$

$Area = 4096.44 \ in^2$

Rounding off to the nearest square inch, we get,

$Area= 4096 \ in^2$

Thus, the area of the circular fire pit is 4096 square inches.

Answer:

A = 125, B = 55, C = 125

Step-by-step explanation:

A line that is cut into two by a line has two angles that equal 180. So angle A + angle D is 180. Angle D = 55 so 180 - 55 = 125. You do the same for every angle but look at the line as being cut into two in different directions for angles a and b and angles c and d.
