Answer:
83 i think. I learned this a while ago so it might be wrong but i believe supplementary angles add to 180 and complementary add to 360 :)
Step-by-step explanation:
y = 1/2x - 7
y = 1/2x + b
-4 = 1/2(6) + b
-4 = 3 + b
-7 = b
7.6 x 10^-4
x=−5
x= 31/21 =1 10/21= 1.476190476
2x+21
hope this helps
