<span>First we define Charlene's the average time, which is (8.4 + 8.6 + 8.3 + 8.5 + 8.7 + 8.5)/6 = 8.5. Normal time is 8.5/1.1 = 7.7. Charlene is faster than normal.</span>
Answer:
It really determines what geometry is.
In simple terms geometry is just shapes.
That’s it really.
You have multiple theorems, postulates, and definitions to help you assist in proofs of theorems or jsut understanding of basic shapes.

Answer:
300tan43 - 300tan40
Step-by-step explanation:
Use tangent to find the height of the building:
tan40 = b/300
b = 300tan40
The use tangent to find the height to the top of the antenna:
tan43 = a/300
a = 300tan43
The antenna height = a - b
