Hi!
Your answers should be : 1. Obtuse | 2. Acute | 3. Obtuse
Here's a little tip for you to remember if you cant get an answer off of brainly: if its 90ft (or degrees or what ever you want to call it) then its right, if its over 90ft its Obtuse, and if its under 90ft its Acute.
Hope this helps!
Let me know if you need anymore help!
Yours truly,
