Answer: 45

Explanation: two angles that form a Line always equal 180 degrees, so we start with the equation 180-u+47, which is the measure of the missing interior angle measure. All of the angles inside of a triangle also equal 180 degrees, so we can set up this equation to find U:
u-18+u+(180-u+47)=180
We can start to simplify by first simplifying what’s inside the parenthesis:
u-18+u+153-u=180
Then you solve the equation to get
U=45 degrees

Isabella painted a water colour design on gridpaper. Some of the points were at A (-4, 8),B (-2, 8), C(-1,6), D (-2, 4), E (-4,

Crank

EXPLANATION

Drawing the line y=3 give us the following graph:

Reflecting over the axis y=3 give us the following image points:

A' = (-4,2)

B' = (-2,-2)

C' = (-1,0)

D' = (-2,2)

E' = (-4,2)

F'= (-5,0)
