Find the perimeter of the triangle.

Mathematics
1 answer:
vagabundo [1.1K]3 years ago
6 0

Answer:

13.83

Step-by-step explanation:

hf =  \sqrt{({6 - 6 })^{2} +( {2 - 5)}^{2}  }

=  \sqrt{0  +  {( - 3)}^{2} }

=  \sqrt{0 + 9}  =  \sqrt{9}  = 3

gf =  \sqrt{ {(6 - 1)}^{2} +  {(2 - 2)}^{2}  }

= \sqrt{ {5}^{2} +  {0}^{2}  }

=  \sqrt{ {5}^{2} }  = 5

gh =  \sqrt{ {(6 - 1)}^{2} +  {(5 - 2)}^{2}  }

=  \sqrt{ {5}^{2} +  {3}^{2}  }

\sqrt{25 + 9}

=  \sqrt{34}  = 5.83

perimeter = 3+5+5.83 = 13.83

The points M(-7,2), N(-3,4), O(-5,8)M(−7,2),N(−3,4),O(−5,8), and P(-9,6)P(−9,6) form a quadrilateral. Find the desired slopes an
pochemuha

The slope of line PO and MN is 0.5. And the slope of the line ON and MP is negative 2. Then each length of the quadrilateral is 4.47 units.

<h3>What is a quadrilateral?</h3>

It is a quadrilateral with four sides. The total interior angle is 360 degrees.

The points M(−7,2), N(−3,4), O(−5,8), and P(−9,6) form a quadrilateral.

Then the slope of each line of the quadrilateral will be

The slope of the line PO will be

PO = (8-6)/(-5+9)

PO = 2/4

PO = 0.5

The slope of the line ON will be

ON = (8-4)/(-5+3)

ON = 4/(-2)

ON = -2

The slope of the line MN will be

MN = (4-2)/(-3+7)

MN = 2/4

MN = 0.5

The slope of the line MP will be

MP = (6-2)/(-9+7)

MP = 4/(-2)

MP  = -2

Then each length of the quadrilateral will be

The length of PO will be

PO = √[(-9+5)² + (6-8)²]

PO = 4.47

The length of ON will be

ON = √[(-5+3)² + (8-4)²]

ON = 4.47

The length of MN will be

MN = √[(-3+7)² + (4-2)²]

MN = 4.47

The length of MP will be

MP = √[(-9+7)² + (6-2)²]

MP = 4.47

What are the eight related addition and subtraction equations for 48, 42, 6
Len [333]

Answer:

Many of these are just the same equation in different orders.

42 + 6 = 48

6 + 42 = 48

48 = 6 + 42

48 = 42 + 6

42 = 48 - 6

48 - 6 = 42

6 = 48 - 42

48 - 42 = 6

alukav5142 [94]

Answer:

answer: b) x = 3, x = -1

Step-by-step explanation:

3|2x - 2| + 6 = 18.

divid by 3 :

|2x - 2| + 2 = 6

add -2 :  |2x - 2|  = 4

2x-2=4 or 2x-2=-4

2x=6 or 2x=-2

x=3 or x=-1
