5. The two figures are scaled copies of each other.

The quadrilaterals are similar and are related by a scale factor, taken from

a specific location, that maps the points on one figure to the other.

a. The scale factor that takes Figure 1 to Figure 2, is 3

b. The scale factor that takes Figure 2 to Figure 1 is \dfrac{1}{3}

Reasons:

From the question, we have that Figure 1 is a scaled copy of Figure 2, therefore;

Let ABCD represent Figure 1, we have;

ABCD ~ PQRS

Length of \overline{AD} = √(2² + 3²) = √(13)

Length of \overline{PS} = √(6² + 9²) = √(117) = √(9 × 13) = 3·√(13)

Therefore;

a. The scale factor that takes Figure 1 to Figure 2, SF₁₂, is therefore;

SF_{12} =  \mathbf{\dfrac{\overline{PS}}{\overline{AD}}}

Which gives;

SF_{12} = \dfrac{3 \cdot \sqrt{13} }{\sqrt{13} } = 3

The scale factor that takes Figure 1 to Figure 2, SF₁₂ = <u>3</u>

(<em>3 times the lengths of Figure 1 gives the lengths on Figure 2</em>)

b. The scale factor that takes Figure 2 to Figure 1, SF₂₁, is given as follows;

SF_{21} = \mathbf{\dfrac{\overline{AD}}{\overline{PS}}}

Which give;

SF_{21} = \dfrac{\sqrt{13} }{3 \cdot \sqrt{13} } =  \mathbf{\dfrac{1}{3}}

The scale factor that takes Figure 2 to Figure 1, SF₂₁ is \underline{\dfrac{1}{3}}

An angle measures 118° less than the measure of a supplementary angle. What is the measure of each angle
Alex787 [66]
Supplementary angles add up to 180°

x = greater supplementary angle
x - 118 = lesser angle

x + (x - 118) = 180
2x - 118 = 180
2x = 298
x = 149

x - 118
149 - 118 = 31

the angles are 31° and 149°

the lenght of an arc in a circle with diameter 10 inches is 1.25π inches. determine the measure of the arc.​
Luda [366]

Answer:

the \:  angle \:  is \:  0.25\pi

Step-by-step explanation:

the arc length is equal to the radius x angle (in radians)

s=ra

s= arc length, r= radius and a= the angle

solve for a ; a= s/r; a=

1.25\pi/5

There are 17 kites in a kite-flying contest at the beach. There are 3 times as many box kites as butterfly kites. There are 2 mo
alina1380 [7]
C is your answer. 5x + 2 = 17

First let’s get them all in terms of x:
Box kites = 3x
Dragon kites = x + 2
Butterfly kites = x

Adding all those up:

x + 3x + x + 2 = 17
Combine like terms:
5x + 2 = 17
