Answer:

Line l (red line): y=4

Line m (black line): y=-2x+4 or y=4-2x

Line n (green line): y=x-1

Line p (blue line): x=-4

Step-by-step explanation:

Line l (red line):

Line l is horizontal. Horizontal lines have y equal to a constant, in this case 4.

y=4

Line m (black line):

Find slope using two points (0,4) and (2,0)

(y2-y1)/(x2-x1)

(4-0)/(0-2)

4/-2

-2

y=mx+c, where m is the slope and c is a number

y=-2x+c

sub in a point (eg (-1,6))

6=-2(-1)+c

6=2+c

c=4

y=-2x+4 or y=4-2x

Line n (green line):

Find slope using two points (3,2) and (2,1)

(y2-y1)/(x2-x1)

(2-1)/(3-2)

1/1

1

y=mx+c, where m is the slope and c is a number

y=1x+c

y=x+c

sub in a point (eg (1,0))

0=1+c

c=-1

y=x-1

Line p (blue line):

X value is constant at -4. x=-4

The sum of the angle measures of a polygon with n sides is 1800. find n
Lilit [14]
The summation of the angle measures of a polygon is given by:
180(n - 2).
Thus, we need to find: 1800 = 180(n - 2)
10 = n - 2
n = 12

Therefore, the shape is a dodecagon, and the number of sides it has is 12.

If a triangle has side lengths 7, 10, and 12, is it a right triangle??
Vesnalui [34]

Answer:

No. Remember, a right angle must have a 90 degree angle. We can find the lengths with the Pythagorean Theorem.

Step-by-step explanation:

Given the length 7, 10, and 12, we can assume that 12 is the hypotenuse (it is the longest length).

- we can use 7 and 10 interchangeably.

Fill in the equation, a^2 + b^2 = c^2

                 where c = 12, and a or b = 7 or 10.

To indicate if the given lengths would form a right angle, we can only input 7 or 10, not both.

Therefore, 7^2 + b^2 = 12^2 or 10^2 + b^2 = 12^2

7^2 + b^2 = 12^2 ==> 49 + b^2 = 144 ==> <u>b= </u>\sqrt{95<u> ==> </u><u>9.746</u>

b= 9.7, not 10.

10^2 + b^2 = 12^2 ==> 100 + b^2 = 144 ==> <u>b = </u>\sqrt{44<u> ==> </u><u>6.633 </u>

b= 6.6, not 7.

Therefore, the lengths 7, 10, and 12, does NOT make a right triangle.

Hope this helps!
