22 pancakes = 8 people
--------------------------------------
Find 1 pancake :
--------------------------------------
1 pancake = 8 ÷ 22
1 pancake = 4/11 of a person
--------------------------------------
Find 55 pancakes :
--------------------------------------
55 pancakes = 4/11 x 55
55 pancakes = 20 people
----------------------------------------------------------------------------
Answer: 55 pancakes can feed 20 people.
----------------------------------------------------------------------------
Same side interior angles have a sum of 180 degrees
49 + x = 180 degrees
x = 180 - 49 = 131 degrees
Solution: 131 degrees
Since the quadrilateral is inscribed inside the circle, where the four vertices are on the circle itself, this means that the opposite angles add to 180 degrees.
Angle I and Angle D are opposite angles. They add to 180 degrees
(angle I) + (angle D) = 180
(45 degrees) + (angle D) = 180
(angle D) + 45 = 180
(angle D) + 45 - 45 = 180 - 45 ... subtract 45 from both sides
angle D = 135
The measure of angle D is 135 degrees
The sr of 22 is 4.69 hope this helps:)
