15^2x is 225x. So, we have 225x-3=245. Adding three to both sides, we get 225x=248. Dividing by 225, we have x=248/225.
Yes, you can see by subtracting 32 from the bottom sides and seeing that the correspondent for 20 degrees celcius is double that of the correspondent for 10 degrees celcius
The angles are 45° 60° and 75°
Elaboration：
Let the three angles be 3x 4x and 5x
( since the sum of interior angles of triangle=180° )
3x+4x+5x= 180
12x = 180
x = 15
3x= 45
4x= 60
5x= 75
