Step-by-step explanation:
use the formula to calculate slope
Answer:
C 80in^2
Multiply 12*3*2 for the area of both sides of the H to get 72
For the middle multiply 2*4 to get 8
72+8=80
The three chords are AB , BD and EF
The five radii are AP, BP, EP, FP and CP
check the picture below.
so it has a base of 18x18 and a height of that much.
x+1/x-1 +1 / x+1/x-1 -1= x
