Set up 2 equations.(x = number of people in first class, y = tourist class)
30x + 25y = 1360
x + y = 52
You have 2 equations and 2 unknown. You can solve them.
I like to use the substitution method
Because y = 52 - x
Then 30x + 25(52 - x) = 1360, solve for x.
30x + 1300 - 25x = 1360
5x = 60
x = 12
Use the x to solve y
30(12) + 25y = 1360
360 + 25y = 1360
25y = 1000
y = 40
False when you multiply numbers you add the exponents.

I would go for Obtuse from the 120° angle, Acute from the either the 20° and 40°, and scalene since all angles are unequal
