The commutative property of addition means we can add two integers in any order. So yes, It would still apply to two negative integers (for example, -2 + -3 and -3 + -2 both equal five)
∠A=36° ∠B=67° measures of a=8
in a Δ sum of all angles are 180
∠A+∠B+∠C=180
36+67+∠C=180
∠C=77
Now use law of sines
a/sinA=b/sinB=c/sinC
8/sin36=b/sin67
now u can find B and C
200+50+4=254 is the answer
