Question

Any idea ? I need help

Answer 1

To answer this question, you must first know the Pythagorean theorem
c^2= a^2 + b^2
The c will always be your hypotenuse and the legs are a and b
c^2=68^2 + 80^2
c^2= 4,624 + 6,400
c^2= 11,024
Now square root both sides
answer is 105 mi  (104.995 if you want it to be exact) 

Answer 2

Use the Pythagorean Theorem:
a^2 + b^2= c^2

a= one side= 68 mi
b= second side= 80 mi
c= hypotenuse= Greenville to Columbia mi


a^2 + b^2= c^2

68^2 + 80^2= c^2
square each number

4,624 + 6,400= c^2

11,024= c^2
take square root of both sides

104.995 mi= c


ANSWER: The distance from Greenville to Columbia is 104.995 miles (rounded to 105 miles).

Hope this helps! :)
