I believe it is an obtuse triangle. Because one triangle is so big there isn’t any 90 degrees and therefor not a right. It might be acute but it had an obtuse side.
Step-by-step explanation: 1st answer is over as it is $19.25 for only the hotdogs. 2nd is $18.50 which is a little over. 3rd one is $22.25. And the forth one is $16.75 which is perfect because he cant buy anything else with the remainder of his money.
