Answer:

y = -47

Step-by-step explanation:

To find the midpoint of two points, add them together and divide by 2

(y+33)/2 = -7

To find y, multiply each side by 2

(y+33)/2 *2 = -7*2

y+33 = -14

Subtract 33 from each side

y+33-33 = -14-33

y = -47

Find the area of a pentagon with an apothem of 7 centimeters

Alexeev081 [22]

If the side length of the pentagon is 19.27 centimeters. Then the area of the pentagon will be 337.225 square cm.

<h3>What is a polygon?</h3>

The polygon is a 2D geometry that has a finite number of sides. And all the sides of the polygon are straight lines connected to each other side by side.

The apothem of the pentagon is 7 cm.

Then the area of the pentagon will be

$\rm Area = 5 \times \dfrac{1}{2} \times apothem \times side \ length$

The side length of the pentagon will be

$\rm Side \ length = 2 \times 7 \tan 54^o \\\\Side \ length = 19.27\ cm$

Then the area will be

$\rm Area = 5 \times \dfrac{1}{2} \times 7\times 19.27\\\\Area = 337.225$

Find the approximate area of the shaded region below, consisting of a right triangle with a circle cut out of it. Use 3.14 as an

Karo-lina-s [1.5K]

Answer:

B. 1,486 metres

Step-by-step explanation:

Find the area of the triangle.

60 x 60 = 3600

3600 ÷ 2 = 1800

Area of triangle = 1800 metres

Area of unshaded circle is approximately 314 metres square using pi

1800 - 314 = 1486

1486 metres square is the approximate area of the shaded region.

What is... X/2 - 13 = 1

kow [346]

X ÷ 2 - 13 = 1
Write the division as a fraction
$\frac{1}{2}x - 13 = 1$
Multiple both sides of the equation by 2
$2 \times \frac{1}{2}x \times - 2 \times 13 = 12$
Reduce the number with greatest common divisor 2
$x - 2 \times 3 = 2$
Multiply the numbers
$- 2 \times 13$
Then u will have
$x - 26 = 2$
Move constant to the right by adding its opposite sides
$x - 26 + 26 = 2 + 26$
Eliminate the opposites
$- 26 + 26$
Then you have
$x = 2 + 26$
Add the numbers
$x = 28$
