Answer:

a) (5,7) b) (7,9)

Step-by-step explanation:

Use the formula xmidpoint= (x1+x2)/2 ymidpoint= (y1+y2)/2

a) xm= (2+8)/2=5

ym=(5+9)/2=7

b) xm=(9+5)/2=7

   ym=(1+17)/2=9

The last part answers the first part for you, just look at the y-values.

In other words:

<em>A'</em><em> </em>(-8, 2)

<em>B'</em> (-4, 3)

<em>C'</em> (-2, 8)

<em>D'</em> (-10, 6)

Explanation:

When you reflect any point over the x-axis, the y-value of the ordered pair is going to change.

This makes sense especially considering that the x-axis is horizontal, so the only way you could cross is to move up or down. If you were to move left or right, you'd only be able to cross the y-axis, since it's vertical.

Now for the last part, as I mentioned above, if you are reflecting across the y-axis, the x-values of the ordered pair is going to change.

<em>A'</em><em>'</em> (8, 2)

<em>B'</em><em>'</em> (4, 3)

<em>C'</em><em>'</em> (2, 8)

<em>D'</em><em>'</em> (10, 6)

Take note that the only thing that changes for the respective value is its sign, while the number itself stays the same.

The sum of the angles of a triangle is 180 degrees. If one of the acute angles of a right triangle is 52 degrees, what is the me
Arada [10]

Answer:

An equation is x+52\°+90\°=180\°

Step-by-step explanation:

Let x be the measure of the unknown acute angle.

According to angle sum property of a triangle, sum of all the angles of a triangle is equal to 180°.

One of the acute angles of a right triangle is equal to 52°.

Also, the triangle is a right angled triangle, one of the angle must be equal to 90°.

x+52\°+90\°=180\°\\x+142\°=180\°\\x=38\°

So, an equation is x+52\°+90\°=180\°
