Answer:
(x - 3, y + 2)
Step-by-step explanation:
When we are translating up/down, we move <em>y</em>.
When we are translating left/right, we move <em>x</em>.
Therefore, if we are moving up 2 and left 3:
Up = +2 to <em>y</em>
Left = -3 to <em>x</em>
(x - 3, y + 2)
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
Answer:
20 floors
Step-by-step explanation:
