Recall that for a polygon to have 180° as the sum of its interior angles, then it must have three sides and thus a triangle. And similarly, for a polygon to have a sum of 360°, it must have four sides or it is a quadrilateral.
[Note that for larger angles, we can apply the formula 180(n - 2) to find the total sum of the interior angles. n is the number of sides]
Now, since we're comparing a four-sided and three-sided polygon, this means that they only differ by 1 side.
Answer: A. 1 side
Two equations are:
Te is time east
Tn is time north
Te + Tn = 5 hours
266Te +196Tn = 1190 is the distance equation
Solve these two equations and
Te = 3 hours and Tn= 2 hours
Perimeter is sum of all the sides.
SO, perimeter of that triangle will be
1/4 + 1/4 + 3/8.
The LCM of denominators (4,4,8) = 8.
Hence writing 1/4 = 2/8.
so,
Perimeter = 2/8+2/8+3/8 = (2+2+3)/8 = 7/8.
So, 7/8 ft is the perimeter of that triangle. :)
