Answer:

Step-by-step explanation:
Since there are 360 degrees in a circle, we can set up the following proportion:

180 minus 90 equals 90, divided by 2, the answer is 45 degrees
Here, 3x + 2y = 12
2x + 2y = 10
Subtract 2nd from 1st equation,
x = 2
Now, substitute in 2nd,
2(2) + 2y = 10
2y = 10 - 4
y = 6/2
y = 3
In short, Your Answer would be: (2, 3)
Hope this helps!
It would be 24 units^2 because the middle is 16 and the two triangles are 4 each
