In the graph below each grid square represents one square yard

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180

step-by-step explanation:

2, 2, 2 or -4, 20, 29

step-by-step explanation:

there is two ways you can do it.

180°

step-by-step explanation:

sum of equilateral triangle=180°

< n=60°

< m=120°°[angle supplementary of equilateral angle]

< m+< r+< x=360°(sum of exterior angle of triangle)

17,000 is the correct answer.
