I would be more than happy to answer, but you have to include your problem!
Answer:
2.5, 5, 7, 8
Step-by-step explanation:
This is the concept of arithmetic; given that a string was cut into 3 equal pieces.
The length of each piece will be:
[length of the string]*3
length of the string=2 1/4 ft=9/4 ft
thus the length will be:
9/4÷3
=9/4×1/3
=3/4 ft
thus we conclude that the length of each string will be 3/4 ft long
Use Pythagorean therom which is
A^2+B^2=C^2
C is the slant (65mi)
A is the vertical line (25mi)
solving for B so the equation is
C^2-A^2=B^2
4225-625=3600
√(3600)= 60
