Answer
The two other sides not labelled have the same length as the side that is labelled, that is, 35 yards.
Step-by-step explanation
An equilateral triangle has all of its sides equal to one another in length.
So, even without the image of the park attached, we can tell that the length of the two other sides that are not labelled is the same as the length of the only side labelled 35 yards.
Hope this Helps!!!
