Hi!
There is a proven rule stating If two chords are congruent, then they are the same distance from the center of the circle.
In this case, the two chords are JR and OE. They are congruent, both being 3.8 units long. Therefore, they are both the same distance from M, the center.
Since both MA and ML intersect the chords JR and OE (respectively), at right angles, and the chords are congruent, then that means ML is congruent to MA.
Hope this helped!
Answer:

Step-by-step explanation:
Here, x represents the number of tickets and y represents the number of T-shirts.
As per the statement:
Each ticket costs $25, and souvenir T-shirts are $12 each
⇒Total cost of ticket = 25x and Total cost for T-shirt = 12y
It is also given that there is a $4 service fee for the entire purchase.

Since, she has $130
⇒
Therefore, an inequality could you use to answer the problem is, 
36/2=18
18 would be your answer the radius is half of the diameter
On an isosceles trapezoid, the two sides that are not parallel to each other will be exactly the same length. If this is true, than it would be create a symetric trapezoid. The diagonals would be the same length. The bases of any trapezoid are parallel, so this is true. The diagonals cannot possibly be perpendicular because the 2 nonparallel sides would be slanted. So, the answer is the 3rd choice.
The area of the ceiling:
A = 14² = 196 ft²
We need plaster to cover 196 ft².
196 : 90 = 2.17778
Answer: We have to buy 3 pails of plaster.
