you have to find how much pabia is making an hour, so you take 270 and divide it by 18. You get 15. So now that you know that Pabia makes 15 dollars an hour, you have to find how many hours he has to work to make 165 dollars. to do that, you take 165 and divide it by 15. you get 11. hope this helps.
Yes you could because the obtuse angle is greater than 90 degrees so if the acute angle is inside the obtuse you could get an right angle or an 90 degree angle
