Step-by-step explanation:

Answer:
Angle A: 45, Angle B: 110, and Angle C: 25.
Step-by-step explanation:
A triangle is 180 degrees total. One angle is 25 degrees. 180- 25 leaves us with 155 degrees. We know that one angle is more than 65 degrees. 155-65 is 90. 90/2 is 45. Therefore, x= 45. Angle A: 45, Angle B: 110, and Angle C: 25. We can double check our work by adding 45+110+25= 180
First you need to find out the remaining value after he bought the calculator this would be 14.67.
60.54 - 45.87= 14.67
Next youll assume the packs of notebooks all cost the same and divide by 3
14.67 / 3 = 4.89
He spent 4.89 on one pack of notebooks
Greatest common factor is 3
