Question 840910: The flower bed in the park by amy's house is in the shAPE of an equilateral triangle. one side of the triangular flower bed is 40 feet long. amy walked around all 3 sides of the triangle. HOW FAR DID SHE WALK?

THE TRIANGLE SHOULD MEASURE 180 ? i THINK ITS IS 180 BECAUSE 40+70+70 = 180

Hi,

equilateral triangle

40+40+40=120

An EQUILATERAL triangle has 3 sides with the same length.
If one side is 40 feet long, the other two sides are 40 feet long too.
The sum of the length of all 3 sides (called the perimeter) of that triangle is
40+feet%2B40+feet%2B40+feet=highlight%28120+feet%29 .
That is the distance Amy walked around the flower bed.

You are confusing problems.
This problem is about an equilateral triangle, with a side measuring 40 feet.
You were thinking of an isosceles triangle, with an angle measuring 40%5Eo .
An ISOSCELES triangle has two sides of equal length, opposite angles of equal measure. In an isosceles triangle with one smaller angle measuring 40%5Eo ,
the other two angles would add up to 140%5Eo , measuring 70%5Eo each.
You knew that because you know that the measures of the angles of a triangle add up to 180%5Eo .
