Answer:
Step-by-step explanation:
2x-y=4 ..........(1)
x+y=5 ...........(2)
<u>Add equation 1 and 2:</u>
We get:
3x=9
x=9/3
x=3
Substitute value of x in (2):
x+y=5
3+y=5
y=5-3
y=2
(3,2)
I think that you forgot to give the picture of the circle along with the question. I am answering the question based on my research and knowledge.
The total unshaded part of the circle = (3/5 + 1/4)
= (12 + 5)/20
= 17/20
Now, the full circle can be considered = 1
Then
The total shaded part of the circle = 1 - (17/20)
= (20 - 17)/20
= 3/20
I hope that this is the answer that has actually come to your desired help.
The Law of Sines states that

Therefore,

Multiply both sides by sin(53):

AB = 17.25
The answer is D) 17
