The area of a trapezium ABCD in which AB || CD, AB = 14 cm, CD = 8 cm. Given

that AB = 23 cm, CD = 7 cm and AD = 17 cm.

Answer:

The area of a trapezium ABCD given the measure of sides is determined by the following equation: A = 1/2 (AD + BC) * h, where h is the height of the trapezium. Using the given information, the area can be calculated as A = 1/2 * (14 + 8) * (23/2) = 200 cm^2.

Answer:

the scale factor is 2

Step-by-step explanation:

The variable x represent the width of the border. Option A is correct.

The space filled by a flat form or the surface of an item is known as the area.

The number of unit squares that cover the surface of a closed-form is the figure's area. Square centimeters is the unit of the area.

The total area of the place mat to include the border is represented by the expression;

(4+2x)(6+2x).

Total area = Surface area+inner area

Hence, option A is correct. The variable x represent the width of the border.

Answer:

160

Step-by-step explanation:

5x-10+12x=16x

17x-16x=10

x= 10

exterior angle at C = 16x= 16×10 = 160°

Answer:

exterior ∠C = 160

Step-by-step explanation:

Exterior angle property: Exterior angle equals the sum of opposite interior angles.

∠A + ∠B = exterior ∠C

5x - 10 + 12x  = 16x  {Combine like terms}

 17x - 10 = 16x         {Add 10 to both sides}

        17x = 16x+ 10         {Subtract 16x form both sides}

17x - 16x = 10

         x = 10

exterior ∠C  = 16x = 16 * 10 = 160

Answer:

75 square feet

Step-by-step explanation:

If you put 3 tables together thats length is 5 square feet you add up the 3 5 feet which is 15 and you multiply that by the 5 on the end and you get 15.

                                                    15 feet

                5 feet                                5 feet                             5 feet

Answer: 39°, 72°, 45°, 150°

Step-by-step explanation:

A circle has 360 degrees. [tex]\frac{1}{360}[/tex] would be equal to 1°

1) [tex]\frac{39}{360}[/tex] would be equal to 39° based on the rule above ^^

2) This fraction has a denominator of 5. Turn the denominator into 360. We can do this by multiplying the bottom by 72, since 360 ÷ 5 = 72 (make sure to multiply the numerator by 72 as well!)

[tex]\frac{1*72}{5*72}[/tex] = [tex]\frac{72}{360}[/tex]

This is equal to 72°

3) Use the same method as before

[tex]\frac{1*45}{8*45}[/tex] = [tex]\frac{45}{360}[/tex]

This is equal to 45°

4) Use the same method as before

[tex]\frac{5*30}{12*30}[/tex] = [tex]\frac{150}{360}[/tex]

This is equal to 150°
