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>
So you need 46 which means that you can’t have less than 46 otherwise you won’t have enough
46/10 = 4 packs + 6 more plates
If you only buy 4 packs you will have 40 plates but you need 46 so buy an extra pack.
So you will need to buy 5 packs of plates.
I hope this helps :)
9.21, 9.22, 9.23, 9.24, or 9.25 would all work.

Answer:
(a) (5π -11.6) ft²
Step-by-step explanation:
The shaded area is the area of 1/5 of the circle less the area of the triangle with base 5.8 ft and height 4 ft.
shaded area = 1/5(π(5 ft)²) -(1/2)(5.8 ft)(4 ft)
shaded area = (5π -11.6) ft²
