The size of the third angle is 102 degrees.
This is because all three angles should always equal 180 degrees. If two of them make up 78 degrees, then you do 180-78 to fine the last angle.
Scientific notatino is
(number that is greater than or equal to 1 and less than 10) times (10^x)
so
318.9
we need to make it less than 10
move decimal 2 places to left
3.189
to make it the same number, we multipl it by 10^2 to make it go back
scientific is
3.189 times 10^2

Answer:
D.
Step-by-step explanation:
area of a square = side^2
area of a cube = 6 x side^2
let the side be a .
6a^2 = 600
=> a^2 = 600/6
=> a^2 = 100
Hence the area of one of its faces is 100 square inches.
or in plain terms without using those formulas,
6 faces of the cube have 600 square inches
=> 1 face of the cube has 600/6 = 100 square inches
