Answer:
Quadrilateral ABCD is inscribed in a circle, then
A + C = 180
=> 2x + 9 + 3x + 1 = 180
=> 5x = 170
=> x = 34
=> A = 2 x 34 + 9 = 77 deg
Hope this helps!

First, you must find the width of GHJK. Since the area of it is 84m², divide 84 by 7.
84÷7=12
So the width of GHJK is 12m.
Next, find the scale of GHJK to LMNP. Since the height of both are already available, you can divide 21÷7 to get 3
This means that to get the width of LMNP you must multiply the width of GHJK by 3.
12×3=36.
Now, to get the area of LMNP, multiply 21 by 36.
21×36=756
So, the area of LMNP is 756m². (Don't forget the units!>
The formula in finding the formula of a decagon is to simply
just add the measurement of all the sides of decagon. A decagon is a shape
having 10 equal sides. To get the length of each side you have to divide 10
from the perimeter.
350 feet / 10 sides = 35 feet each side
Therefore, the length of each side is 35 feet.
Ultimately, you are trying to find 2/3 of 1/4 because that is how much you want to feed him. So simply multiply and simplify them. 1/6 is 2/3rds of 1/4
