Y-9 + y/2 = 180
Add nine to each side
y+y/2=189
Multiply each side by two
2y+y=378
Add the y's together
3y=378
Divide it all by three
y=126
so, Angle B is 126 degrees
I hope that helps!
Answer:
length = 9, width = 7
Step-by-step explanation:
length = l, also w+2 width = w
perimeter = 2w + 2l
create an equation: 32 = 2(w) + 2(w+2)
simplify
32 = 2w+2w+4
32 = 4w+4
28=4w
w=7
solve for length
l = w+2
l=7+2
l=9


Both points are on the graph.
