Answer: The sides are increase by a factor of 3 and the angles remain the same.

When you are performing a dilation, you multiply the coordinates by 3. This will increase the length of all the sides by a factor of 3. However, the measures of the angles will remain the same. We call these similar figures.

The side lengths of the following right triangle 15,20 and 25, as shown below. The altitude from the right angle splits the hypo

kompoz [17]

Answer:

$h = 12$

$x = 9$

$y= 16$

Step-by-step explanation:

Given

The attached triangle

Required

Find h, x and y

Let the base of the triangle be 15.

So, the area is:

$A = \frac{1}{2} * 15 * 20$

$i.e\ height = 20$

$A = \frac{1}{2} * 300$

$A = 150$

Let the base of the triangle be 25.

So, the area is:

$A = \frac{1}{2} * 25 * h$

$i.e\ height = h$

$A = \frac{1}{2} * 25h$

Substitute $A = 150$

$\frac{1}{2}*25h = 150$

Solve for h

$h = \frac{150 *2}{25}$

$h = 6 *2$

$h = 12$

Considering the smallest triangle

$Hypotenuse = 15$

So:

$15^2 = h^2 + x^2$

$15^2 = 12^2 + x^2$

This gives:

$15^2 - 12^2 = x^2$

$81 = x^2$

Take square roots

$9 =x$

$x = 9$

Solving for y

$x + y = 25$

$y= 25 - x$

$y= 25 - 9$

$y= 16$

Holly missed 7 of 185 school days this year. Approximately what percent of school days was Holly in attendance?

Alexandra [31]

185-7=178
So 178÷185=0.9621621
0.96×100=96%
OR APPROXIMATELY 96 percent

Answer: x = -5

Step-by-step explanation:

1) subtract 4 from both sides (-5x = 25)

2) divide -5 from both sides (x = -5)

Then you have the answer!
