The perimeter is 64 yards.
Answer:
I think it is a 160o Angle
Step-by-step explanation:
Y=mx+b
b represents your y-intercept
mx represents your slope
U can show your work by underlining what your rounding and showing which place it is it the right of it but there is no mathematical work
A+b+c = 131
b = 7 + 2a and c = a - 12
so a + 7+2a + a-12 = 131
then 4a -5 = 131
then 4a = 136
and a = 34....so b= 75 and c = 22....check 34+75+22=131√
