Answer:
See below.
Step-by-step explanation:
There are 4 sides of the pyramid that rise from the 4 points on the base and they all meet at the point A.
So it has 1 square face ( the base) and 4 side faces which are all triangles.
1.0769
multiply 4x2 to get 8
move -52x over the equal sign to make it 52x
so we get something like this: 8 + 169 = 121 + 52x
also move 121 over the equal sign to make it -121
Like this: 8 + 169 - 121 = 52x
Now when you simply, you will get 56 = 52x
Divide both sides by 52
Final answer is 1.0769
