What is the area of this polygon?
mart [117]

The area of the polygon is the sum of the area of rectangle + area of triangle = 316 cm². (Option C)

<h3>Area of Polygon</h3>

The polygon is composed of a triangle and a rectangle.

Area of the polygon = Area of Triangle + Area of Rectangle

Area of Rectangle = length × width

Length = 21 cm

Width = 14 cm

Area of rectangle = 21 × 14 = 294 cm²

Area of Triangle = 1/2(base × height)

Base = 21 - 10 = 11 cm

Height = 18 - 14 = 4 cm

Area = 1/2(11 × 4) = 22 cm²

Therefore:

Area of Polygon = 294 + 22 = 316 cm².

5. The measures of angles of hexagon are 4x, 5x, 6x, 7x, 8x and 9x. Calculate the size of the largest angle
Amiraneli [1.4K]

Answer:

166 2/13 deg

Step-by-step explanation:

The sum of the measures of the interior angles of a convex polygon of n sides is 180(n - 2).

A hexagon has 6 sides, so n = 6.

sum of measures of angles = 180(n - 2) = 180(6 - 2) = 180(4) = 720

4x + 5x + 6x + 7x + 8x + 9x = 720

39x = 720

x = 720/39

x = 240/13

The largest angle has measure 9x.

9x = 9 * 240/13 = 2160/13

2160/13 = 166 2/13

Answer: 166 2/13 deg

vodka [1.7K]

Let 'x' represent the monthly membership fee for the gyp.

Since 1 year = 12 month for 1 year Alyson will pay 12x dollars.

But if she pay in advance 12x dollars she will receive $50 discount and pay $514:

12x - 50 = 514

 

x = $47

The monthly membership fee is $47.
