Answer:
46
Step-by-step explanation:
all triangles add up to 180 degrees
add up the degrees that are given
83+51=134
SUBTRACT 134 from 180 which would be 46
add up all the degrees and they should add up to 180 to double check your work!
6*6.5 = 39
then divide by 2 because he's splitting it.
39/2=19.5
so even if he want soil for both sides, its only 1 bag, cause 1 bag covers 40 yards.
