Answer:
144°
Step-by-step explanation:
step 1
Find the measure of the central angle of the regular pentagon
Divide 360 degrees by 5 (the number of sides)

Let
c----> the center of the pentagon
we know that
m∠ECA=72°
m∠ACB=72°
therefore
m∠ECB=m∠ECA+m∠ACB
substitute the values
m∠ECB=72°+72°=144°
The measure of angle ECB is equal to the degrees that the pentagon rotate
Dont u think their should be more points for 4 hard questions
The bottom 2.
I can’t see the point names cause its blurry but those bottom 2 points should be the answers.
Y coordinates are how high or low
X coordinates are how far left or right
