Great question! You can pick a different angle if you’d like and still reach a correct answer based off of your decision of where to put theta. The reason I picked theta to be where to be there was based off of the convention from previous examples such as example 2.2. But you’re free to use a different convention so long as you’re consistent:)
Why sin theta? Why did we pick that angle ? Please explain 😭😭😭😭
