A tetrahedron is a triangular pyramid. It has four triangular faces and four vertices.
In the question, we are told that the length of the edges are all equal = 20m and the length from one corner to the center of the base = 11.5m
We sketch a diagram of a tetrahedron with the given measurement as shown below
To find the height, we will use the Pythagoras theorem
20² = h² + 11.5²
h² = 20² - 11.5²
h² = 267.75
h = √267.75
h = 16.36 (rounded to two decimal places)
Answer:
93 degrees
Step-by-step explanation:
first, lets add 38+49 to see the sum
38+49=87
since the sum of all three angles in every triangle equals 180, we can subtract this sum from 180 to get the answer
180-87=93
so the missing angle would be 93
It can be defined as a positive..
it is also a inverse function to the natural exponential function
i hope that helps
For the first one is definitely 0.12
The second one I was having trouble with, but I know it is not .25 or .75. Looking at the leftover answers I would say .36 because I already used .12. Also .52 and .25 are the givens.
