An aquarium tank in the shape of a rectangular prism is 60 cm long, 27 cm wide, and 24 cm high. the top of the tank is open, and
the glass used to make the tank is 1 cm thick. the volume for the aquarium is 33,350 cm3. what if, to provide greater strength, the glass bottom were increased to a thickness of 4 cm? how much less water would the tank hold?

Let x = second angle
let x + 10 = first angle
let 2( (x) + (x+10) ) = third angle.
Since the interior of a triangle equals 180° then,
Inputting the value of x gives us each angle.
second angle = 25°
first angle = x + 10 = 25 + 10 = 35°
third angle = 2( (x) + (x+10) ) = 2( (25) + (25+10) )
= 110°
let x + 10 = first angle
let 2( (x) + (x+10) ) = third angle.
