Find the area to the nearest square foot of the shaded region below, consisting of a square with a circle cut out of it. Use

Simora [160]

Answer:

the area is 10 feet by 10 feet, 100 feet²

subtract the area of the circle from this.

you get it by A = r² * pi

so 5² * 3.14159...

=78.5398163397

100-78.5398163397

is roughly 21.46 square feet

For a regular 36-gon, what is the sum of measure of each interior angle?

ser-zykov [4K]

Answer:

170°

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2)

Here n = 36, thus

sum = 180° × 34 = 6120°

The size of each interior angle = $\frac{6120}{36}$ = 170°

Johnny's town is having an old-fashioned circus under a large tent. In order to keep the tent from falling down, workers must ti

Zepler [3.9K]

Answer: 62 feet approximately.

Step-by-step explanation:

1. Based on the information given in the problem, you can draw a right triangle as the one shown in the image attached, where the height of the tent is represented with $x$ . Therefore, you can calculate it as following:

$sin\alpha=\frac{oppostite}{hypotenuse}$

Where:

$\alpha=62\°\\opposite=x\\hypotenuse=70$

2. Substitute values and solve for $x$ , then the height of the circus tent is:

$sin(62\°)=\frac{x}{70}\\x=70*sin(62\°)$

$x=61.81$ ≈ $62ft$

Two bird watchers position themselves at point A (the beach) and point C (the shed) which are 111 feet apart. The both spot a ra

o-na [289]

Answer:120 ft

Step-by-step explanation:

Given

Beach(A) and Shed (C) is $111$ feet apart

If Two bird watchers set then at A and C and observe a bird at $94^{\circ}$ and $46^{\circ}$

Using Trigonometric relation

$\tan 86=\frac{h}{x}---1$

$\tan 46=\frac{h}{111+x}---2$

from 1 and 2

$x\tan 86=(111+x)\tan 46$

$x=8.66\ ft\approx 9\ ft$

Therefore bird is $120\ ft$ from point C
