The total amount of degrees in a triangle is 180. All three angles should add up to 180˚
We know that 40+60 = 100
The next step is to do 180-100 to get the other angle.
180-100 = 80
So the measure of the third angle is 80˚
Hope this helps!
(Also if you want to do this in one equation, you would do 40+60+x = 180
40+60+x = 180
100+x = 180 (combine like terms)
x = 80 (Subtract 100 from both sides)
(25-y) ^2-y^2=25
y=12
x=25-12
x=13
(13,12)

Answer:
14 cm.
Step-by-step explanation:
We have been given that an aquarium is a right rectangular prism 18.5 cm long and 15 cm wide. We are also told that Martene put 3885 cubic cm of water in the aquarium.
To find the depth or height of aquarium, we will use volume of rectangular prism formula.
, where,
l = Length of prism,
w = Width of prism,
h = Height of prism.
Upon substituting our given values in above formula we will get,
Therefore, the aquarium is 14 cm deep.
