Answer:
f = 48/5
Step-by-step explanation:
5f = 12 * 4
5f = 48
f = 48/5
The answer is A ( need points)
Answer:
100 ft
Step-by-step explanation:
We need to find the diagonal ( or hypotenuse)
We can use the Pythagorean theorem
a^2+b^2 = c^2 where a and b are the legs and c is the hypotenuse
80^2 + 60^2 = c^2
6400+3600 = c^2
10000 = c^2
Taking the square root of each side
sqrt(10000) = sqrt(c^2)
100 = c
Multiply the second equation by -2. This will cancel out the y
