Answer:

Step-by-step explanation:

Since all the points were shifted the same way, I'll just use point A and point A'.

Point A starts at (3,5) and A' is at (5,2)

If the subract the x coordinates: 5-3=2

Then subtract the y coordinates: 2-5=-3

The 2 is positive, so it is 2 units to the right (the positive x direction) and -3 is negative so 3 units down (negative y direction)

Find the value of x.

svetoff [14.1K]

Answer:

x = 28

Step-by-step explanation:

The ratios of corresponding sides are equal, that is

$\frac{12}{8}$ = $\frac{x-7}{14}$ ( cross- multiply )

8(x - 7) = 168 ( divide both sides by 8 )

x - 7 = 21 ( add 7 to both sides )

x = 28

In the diagram, is the perpendicular bisector of and is also the angle bisector of . If m = x, which quantity is equal to sin ?

earnstyle [38]

Given that line PN is a perpendcular bisector of line AB, then angles APN and BPN are equal to 90 degrees each.

Also, given that line PN is an angle bisector to angle CPD and angle CPD measures x, then the measure of angle DPN is $\frac{1}{2} x$ .

Thus, the measure of angle DPB = angle BPN - angle DPN
$=90- \frac{1}{2} x$

Therefore,
$\sin DPB=\sin\left(90- \frac{1}{2} x\right) \\ \\ =\sin(90)\cos\left(\frac{1}{2} x\right)-\sin\left(\frac{1}{2} x\right)\cos(90) \\ \\ =\cos(\frac{1}{2} x)$

Jack wants to plant a border of flowers in the shape of an arc along the edge of a circular walkway. of the circle has a radius

Jet001 [13]

To solve this problem you must apply the proccedure shown below:

1. You must apply the formula for calculate the arc length, which is:

arc length=(angle)(radius)

2- As you can see, <span>the circle has a radius of 5 yards and the angle subtended by the arc measures 1 1/2 radians. Therefore, you have:
</span>
The angle is:

1 1/2 radians=1.5 radians

3. When you susbtitute these values into the formula, you obtain:

arc length=(1.5 radians)(5 yards)
arc lenght=7.5 yards

4. Therefore, the answer is: 7.5 yards.
