Answer:
105°
Step-by-step explanation:
X and 75 has to add up to 180
so 180 - 75 = 105°
Answer:
20
Step-by-step explanation:
The area of a circle is equal to pi*radius^2
We can then write this as
314.1592=π*r^2
We then divide pi to get
100=r^2
take the square root and you find that the radius equals around 10
The diameter is always equal to the radius times two which means that the diameter is 20

There are 7 faces, 12 edges and 24 vertices in a hexagonal pyramid.
-13<w because 9*w and 9*3 = 90>-9w-27 then add 27 and get 117>-9w then divide and get -13<w
