Answer:

432 ft^2

Step-by-step explanation:

Answer:

432

Step-by-step explanation:

Lets plug it into the formula

b1 should be the horizontal line on the bottom horizontal line and b2 should be the top horizontal line

so we get b1 = 28 and b2 = 20

according to the formula we should add b1 and b2, getting us 48.

divide 48 by 2: we get 24

24 times h, or the hieght, or 18 is 432

so the answer is 432

14. A polygon ABCD is inscribed in a circle. Find angle ABC15. A polygon GHIJ is inscribed in a circle if GHI=76 and HIJ=66 what is IJG

Answers

Answer:

m<ABC = 100degrees

m<IJG = 104degrees

Step-by-step explanation:

14. The sum of the opposite angle of the quadrilateral is 180degrees. Hence;

m<ADC + m<ABC = 180

3y+8+4y+4 = 180

7y + 12 = 180

7y = 180 - 12

7y = 168

y = 168/7

y = 24

Get <ABC

m<ABC  = 4y+4

m<ABC = 4(24) + 4

m<ABC = 96 + 4

m<ABC = 100degrees

15. Similarly for this;

GHI + IJG = 180

76 + m<IJG = 180

m<IJG = 180 - 76

m<IJG = 104degrees

Find the slope of the line that passes through the points (3, 2) and (-2, -2). 5/4 4/5 -4

Answers

Answer:

m = 4/5

Step-by-step explanation:

m = slope

m=(y_2-y_1)/(x_2-x_1)

m=(-2-2)/(-2-3)

m=(-4)/(-5)

m=(4)/(5)

What part of the coordinate plane is equidistant from the points a(-3,2) and b(3,2)?

Answers

We first find the midpoint of the points:
Midpoint: ((3-3)/2 , (2 + 2)/2)
= (0 , 2)
Thus, the y-axis, where x = 0, is equidistant from the two points.

Answer:

The y-axis is  equidistant from both points

Step-by-step explanation:

 we know that

The formula to calculate the coordinates of midpoint M between two points is equal to

M=((x1+x2)/(2), (y1+y2)/(2))

we have

(x1,y1)=(-3,2)

(x2,y2)=(3,2)

substitute the values in the formula

M=((-3+3)/(2), (2+2)/(2))

M=(0,2)

see the attached figure to better understand the problem

The y-axis is  equidistant from both points
