Count the number of layers in the pyramid. Here's the answer, starting with one layer. 1 layer =1 ball, 2=5, 3=14, 4=30, 5=55, 6=91, 7=140, 8=204, 9=285, 10=385. If you have a larger pyramid, just keep squaring the number of each additional layer and add that number to the previous layer total. Bobby

The total number of degrees in any triangle is 180 degrees. For example, a right-angled triangle will have a 90 degree corner and two 45 degree corners.
A triangle
The total number of degrees in a triangle is 180. this will not change no matter what type of triangle it is. (obtuse, acute, right angle, etc)
4
Six
The 3 interior angles of any triangle add up to 180 degrees
4
180 degree.
Depends on the type of triangle. A right-angled triangle has ONE right angle - the remaining two angles total 90 degrees.
In total, a triangle has 180 degrees.
Oh, dude, let me break it down for you. So, the probability of selecting a white ball from that colorful box is simply the number of white balls divided by the total number of balls in the box. In this case, there are 5 white balls out of a total of 5 white + 8 red + 10 yellow balls. So, the probability is 5/23. Easy peasy, lemon squeezy!
