Answer:

108

Step-by-step explanation:

Interior angles in a pentagon add up to 540 degrees. So we first need to find the total sum of all the known angles. We do this by calculating 104+108+112=324.

Now we need to find the total sum of the unknown angles, and we do this buy calculating 540-324=216.

The final step is to find the size of one of the 2 remaining angles, and since we know they are equal, we just have to divide by 2. So, 216/2=108. This is our final answer.

Rotation 90 degrees counterclockwise about the origin

nataly862011 [7]

Answer:

Point W = (-3, 3)
Point X = (-3, 2)
Point V = (-2, 3)

The rotation rule states that rotation 90° counterclockwise means (x, y) = (-y, x)

The new points would be equal to:

Point W' = (-3, -3)
Point X' = (-2, -3)
Point V' = (-3, -2)

Try graphing it to see if the new points make sense(because I'm not too sure :\)
