Please please find the area for this polygon!

Answers

Answer:

508

Step-by-step explanation:

28*16= 448

6*6= 36

4*6= 24

448+36+24= 508

In order to find the area of a polygon, all you have to do is follow the formula: area = 1/2 x perimeter c apothem. To sum it together, perimeter = the sum of the lengths of all the sides. So add 6, 16, 16, 6, 4, 6, 28, and 18! And then you have 100! Then multiply it by 1/2! So your answer should be 50. Please consider brainliest.

Answer:

65°

Step-by-step explanation:

the angle of a straight line has to add up to 180°

if it doesn't, it's not a straight line

115° and x are supplementary angles

meaning we know they have to add up to 180°

so simply subtract

180- 115 =

65°

you can check work by adding

115+65= 180

Answer: 65

180-115=65

Step-by-step explanation:

A straight line is always 180 so I subtracted 115 from 180.

The semicircle below has a diameter of 20. Find the area of the blue region.

Answers

Answer:

61

Step-by-step explanation:

Use the area of semicircle minus the area of the triangle. Area of the semicircle is 10^2 * pi / 2 = 50 pi, the area of the triangle is 12*16/ 2 = 96. The the area for the blue part is 50 pi - 96 = 61.07963268 or 61.

If it is helpful, plz give me Brainliest.

Answer:

50pi - 96

Step-by-step explanation:

The radius of the semicircle is 10, so the area of the entire semicircle is 1.2*10^2 pi = 50pi

The white triangle has an area of 1/2*12*16 = 96 so subtracting it shows that the blue area is 50pi-96
