Find the approximate perimeter of △ABC plotted below.
pickupchik [31]

Answer:

The perimeter of triangle ΔABC is approximately;

(A) 20.0

Step-by-step explanation:

In ΔABC, the coordinates of the vertices are given as follows;

A(-4, 1), B(-2, 3), C(3, -4)

The length, 'l', of the sides of the triangle with known 'x', am]nd 'y' coordinates are given as follows;

l = \sqrt{\left (y_{2}-y_{1}  \right )^{2}+\left (x_{2}-x_{1}  \right )^{2}}

Therefore, we have;

The length of segment \overline {AB} = √((3 - 1)² + (-2 - (-4))²) = 2·√2 ≈ 2.83

The length of segment \overline {BC} = √(((-4) - 3)² + (3 - (-2))²) = √74 ≈ 8.6

The length of segment \overline {AC} = √(((-4) - 1)² + (3 - (-4))²) = √74 ≈ 8.6

The perimeter of a geometric shape is equal to the sum of the length of sides of the figure

The perimeter of triangle ΔABC = (The length of segment \overline {AB}) + (The length of segment \overline {BC} ) + (The length of segment \overline {AC})

∴ The perimeter of triangle ΔABC = 2·√2 + √74 + √74 ≈ 20.0.

An architect wants to draw a rectangle with a diagonal of 15 centimeters. The length of the rectangle is to be 6 centimeters mor
S_A_V [24]

Answer:

She should make a rectangle with dimensions 14.4 cm by 4.2 cm.

Step-by-step explanation:

  • The diagonal of a rectangle is represented by \sqrt{length^2+width^2}.
  • Area of rectangle is = length×width
  • Perimeter of a  rectangle = 2(length+width).

Assume x be the width of the rectangle.

The length of the rectangle is to be 6 cm more than twice the width.

The length of the rectangle is= (2x+6) cm

Then the diagonal of the rectangle is \sqrt{length^2+width^2}

                                                             =\sqrt{(2x+6)^2+x^2}

                                                            =\sqrt{4x^2+24x+36+x^2}

                                                             =\sqrt{5x^2+24x+36} cm

According to the problem,

\sqrt{5x^2+24x+36}=15

Squaring both sides

\Rightarrow{5x^2+24x+36}=15^2

\Rightarrow{5x^2+24x+36}=225

\Rightarrow{5x^2+24x+36-225=0

\Rightarrow{5x^2+24x-189=0

⇒5x²+45x-21x-189=0

⇒5x(x+9)-21(x+9)=0

⇒(x+9)(5x-21)=0

⇒x+9=0  or,   5x-21=0

\Rightarrow x=-9, \frac{21}5

⇒x= -9, 4.2

Since the width of a rectangle can not negative.

So, x=4.2 cm

The width of rectangle is = 4.2 cm

The length of the rectangle is =(2×4.2+6)

                                                  =14.4 cm

She should make a rectangle with dimensions 14.4 cm by 4.2 cm.

Help out please thank you
Helga [31]

Answer:

x = 26

Step-by-step explanation:

The three angles form a straight line, so they will sum to 180

4x - 8  + 34  + 76- x = 180

Combine like terms

3x+ 102 = 180

Subtract 102 from each side

3x+102-102 = 180-102

3x= 78

Divide each side by 3

3x/3 = 78/3

x = 26
