Angles ACD and ACE are supplementary. They combine to form a straight angle which is 180 degrees. Let x be the measure of angle ACE.
----
(angle ACD) + (angle ACE) = 180
100 + x = 180
x = 180-100 .... subtract 100 from both sides
x = 80
<h3>angle ACE is 80 degrees</h3>
Answer:
Perpendicular

Answer:
1920
Step-by-step explanation:
Simple, you are adding a negative to a positive, so think of it as a subtraction, 5/6 - 2/3 = .
