24 is the answer for your problem
Answer:
d
Step-by-step explanation:
A rectangle has a right angle in every corner, so you would need to subtract the current angle from 90 to find the angle required.
Pytagorean theorem
height10
attached at 10-4=6 yards from bottom
8 yards from base to away
a^2+b^2=c^2
a and b are side legnths and c=hypotonuse
so therfore we are given a and b and we must solve for c
so
6=height
8=base
6^2+8^2=c^2
36+64=c^2
100=c^2
square root
10=c
so therfor the legnth of each cable is 10 yards
3 cables so 3 times 10=30
30 yards needed
You would graph it by starting at (0,4) and then move (1,-7) in the positive and (-1,7) in the negative
