X=3
Explanation:
A straight line equals 180°, and they give you the one angle of 56°, so you know 56+ the other equation has to equal 180
56+4x+112=180
168+4x=180
Subtract 168 from both sides
4x=12
Divide 4 from both sides
X=3
You can check by filling it in.
56+4*3+112=
12+56+112=180
Yes because 4 times 5 is 20 and 15 + 5 is 20

(1) will write us of the following form
![\dfrac{dy}{dx}+y^2\sin x=0\\ \\ ](https://tex.z-dn.net/?f=%5Cdfrac%7Bdy%7D%7Bdx%7D%2By%5E2%5Csin%20x%3D0%5C%5C%20%5C%5C%0A)
(2) [do not it need explanation]
![\dfrac{dy}{dx}=-y^2\sin x\\ \\ ](https://tex.z-dn.net/?f=%5Cdfrac%7Bdy%7D%7Bdx%7D%3D-y%5E2%5Csin%20x%5C%5C%20%5C%5C%0A)
(3) Left place variable "y" and right place, variable "x" like this
![\dfrac{dy}{y^2}=-\sin x\, dx\\ \\](https://tex.z-dn.net/?f=%5Cdfrac%7Bdy%7D%7By%5E2%7D%3D-%5Csin%20x%5C%2C%20dx%5C%5C%20%5C%5C)
(4) Integrate both members
![\displaystyle \int \dfrac{dy}{y^2}=\int-\sin x\, dx\\ \\](https://tex.z-dn.net/?f=%5Cdisplaystyle%0A%5Cint%20%5Cdfrac%7Bdy%7D%7By%5E2%7D%3D%5Cint-%5Csin%20x%5C%2C%20dx%5C%5C%20%5C%5C)
(5) Solve us the integrals
![-\dfrac{1}{y}= \cos x+C](https://tex.z-dn.net/?f=-%5Cdfrac%7B1%7D%7By%7D%3D%20%5Ccos%20x%2BC)
(6) Isolate variable "y"
![\boxed{y=-\dfrac{1}{\cos x+C}}](https://tex.z-dn.net/?f=%5Cboxed%7By%3D-%5Cdfrac%7B1%7D%7B%5Ccos%20x%2BC%7D%7D)
