Answer:
AA similarity
Step-by-step explanation:
Using angle sum theorem, you can clearly find out the missing angles on the left and right triangles are 40° and 50° respectively.
Therefore, by using any two angles in the triangles, you can prove they are similar by AA similarity.

ANSWER
The particular solution is:
![y=2-2 \cos(x)](https://tex.z-dn.net/?f=y%3D2-2%20%5Ccos%28x%29)
EXPLANATION
The given Ordinary Differential Equation is
![y'=2 \sin(x)](https://tex.z-dn.net/?f=y%27%3D2%20%5Csin%28x%29)
The general solution to this Differential equation is:
![y=C-2 \cos(x)](https://tex.z-dn.net/?f=y%3DC-2%20%5Ccos%28x%29)
To find the particular solution, we need to apply the initial conditions (ICs)
![y( \frac{\pi}{3} ) = 1](https://tex.z-dn.net/?f=y%28%20%5Cfrac%7B%5Cpi%7D%7B3%7D%20%29%20%3D%201)
This implies that;
![C-2 \cos( \frac{\pi}{3} ) = 1](https://tex.z-dn.net/?f=C-2%20%5Ccos%28%20%5Cfrac%7B%5Cpi%7D%7B3%7D%20%29%20%3D%201)
![C-2( \frac{1}{2} )= 1](https://tex.z-dn.net/?f=C-2%28%20%5Cfrac%7B1%7D%7B2%7D%20%29%3D%201)
![C-1= 1](https://tex.z-dn.net/?f=C-1%3D%201)
![C= 1 + 1 = 2](https://tex.z-dn.net/?f=C%3D%201%20%2B%201%20%3D%202)
Hence the particular solution is
![y=2-2 \cos(x)](https://tex.z-dn.net/?f=y%3D2-2%20%5Ccos%28x%29)
