Help me with the angle measures please!!

So first off, lets start off with what we know:

The total sum of the angles in a triangle is always 180 degrees.

Angle A = 60 degrees. (They told us so in the picture!)

That means that:

Angle B + C = (x + 20) + 3x

And B + C = 180 - 60 = 120 degrees.

Therefore (x + 20) + 3x = 120 degrees.

So it follows that if we simplify we get:

4x + 20 = 120 degrees

4x + 20 - 20 = 120 - 20

4x = 100 degrees

x = 25 degrees.

Then we know that:

B = 3x = 3 * 25 = 75 degrees.

And:

C = x + 20 = 25 + 20 = 45 degrees.

We can check by doing:

95 + 75 + 60 = 180 degrees!

So we have solved the problem.

The answer can be found in Sir Isaac Newton's First Law of Motion. According to this law, an object at rest (like the egg sitting on the tube) should stay that way unless a force pushes or pulls it (your hand striking the pie pan). ... Then another force—gravity—took charge and pulled the egg straight down into the glass.
