Trigonometry question

ehidna [41]

Answer:

The scale factors that make figure smaller are the option D. -0.5 and the option E. 0.25

Step-by-step explanation:

we know that

If the absolute value of the scale factor is greater than 1, then the image will be larger than the pre-image.

If the absolute value of the scale factor is less than 1, then the image will be smaller than the pre-image.

If the absolute value of the scale factor is equal to 1, then the image will be the same size than the pre-image.

Additionally, a negative scale factor causes the dilation to rotate 180 degrees

therefore

In this problem

The scale factors that make figure smaller are the option D. -0.5 and the option E 0.25

Which construction is being shown in the diagram?

Answer:

Correct answer is option D) Construct the bisector of an angle.

Step-by-step explanation:

Angle bisector of an angle is a line that divides the angle in two equal parts.

A Line BD is called the angle bisector of $\angle ABC$ if

$\angle ABD = \angle CBD$

Please refer to image attached.

As per the question image, if the line PW is joined it will be the angle bisector of $\angle QPR$ .

Steps of construction of angle bisector:

1. Draw the angle QPR.

2. Open compass and make an arc that will cut the two lines on points Q and R respectively as shown in question figure.

3. With the same compass opening, put the compass on Q and make an arc in the area between $\angle QPR$ .

4. Draw an arc keeping the compass on R to cut the previous arc on point W.

Line joining the points P and W is the angle bisector of $\angle QPR$ .

So, Correct answer is option D) Construct the bisector of an angle.

3.14 is used for pi.

6. r = $\sqrt{\frac{A}{\pi } }$

14.00

7. d = $\frac{c}{\pi }$

5.00

8. d = $2 \sqrt{\frac{A}{\pi } }$

23.01

9. r = $\frac{c}{2\pi }$

20.01

10. d $\pi$ = $2 \sqrt{{A}$

31 $\pi$

11. r $\pi$ = $\frac{c}{2}$

22.5 $\pi$

Hope this helps :)
