Answer:

It was used    \frac{1}{3}   as scale factor.  

Step-by-step explanation:

The scale factor is the ratio of two corresponding side lengths of similar figures. Similar figures have the same shape but are of different sizes.

To find the scale factor that was used when going from the grey triangle to the yellow triangle we can work with any of the three sides of the grey triangle.

Let's work with the below side.

The below side is extended from the point (-2,4) to the point (7,4)

The length of this side is 9 units.

In the yellow triangle, we can see that the below side is extended from the point (2,0) to the point (5,0)

The length of this side is 3 units.

Working with the lengths and the scale factor ⇒

(9units).(ScaleFactor)=3units

ScaleFactor=\frac{3units}{9units}=\frac{1}{3}

We find that the scale factor that was used when going from the grey triangle to the yellow triangle is \frac{1}{3}

Quadrilateral ABCD is inscribed in the circle. Which sentence is true?
astra-53 [7]

Answer:

A) A and B are supplementary

Step-by-step explanation:

we know that

For any inscribed  quadrilateral in the circle , opposite angles will be supplementary

so

In this problem

Angle A and Angle B are supplementary angles

m\angle A+m\angle C=180^o

Angle B and Angle D are supplementary angles

m\angle B+m\angle D=180^o

therefore

<u><em>The sentences that are true </em></u>

A) A and B are supplementary
