Answer: 180 degrees</h3>
note: it doesn't matter if its clockwise or counterclockwise when it comes to 180 degree rotations.
========================================
Explanation:
The rule for 180 degree rotations is
(x,y) ---> (-x, -y)
So the x and y coordinates flip in sign from positive to negative, or vice versa.
Point D ' (-3, 5) rotates to D ' (3, -5) following this rule
-----------------
A further detailed break down might look like this
x = -3 becomes -x = -(-3) = 3
y = 5 becomes -y = -5
(-3, 5) ----> (3, -5)
keep in mind that, a negative coefficient to "x", will make the graph reflect over the y-axis.
Answer:
Vertical angles are congruent, so L3 = 37 degrees, and L4 = 143 degrees.
Let me know if this helps!
