Answer:
102
Step-by-step explanation:
triangle area = 180 degrees
straight line = 180 degrees
180 - 127 = 53
49
49 + 53 + 3rd angle = 180
3rd angle = 78
180-78 = x
x = 102
Ray CD cuts angle PCR in half.
PCD = 35 degrees.
So, RCD = PCD or 35 degrees.
Answer:
Step-by-step explanation:
In order to calculate the volume of a triangular prism you need 2 things:
The triangles area and the prism's height.
Any prism's volume can be calculated by multiplying its base area with its height.
The Area of a triangle can be calculated in different ways.
The most used and "normal" way is:
(width * height) / 2
Another way is by using herons formula, which looks like this:
a, b, c = different sides of the triangle (length)
s = (a + b + c) / 2
a = 
When you have the prism's base area (
) you just have to multiply:

(V = volume)

Because the numerater and denomenater are = hence 1/1, 2/2, 3/3, 4/4 5/5, 6/6, 7/7, 8/8, etc. are all = to one
hope this helps :)
