Answer:
c the answer is c
Step-by-step explanation:
Formula for midpoint between two points is M(x,y)
x=(x1+x2)/2 and y=(y1+y2)/2
In our case (x1,y1)=(m,b) and (x2,y2)=(0,0)
x=(m+0)/2=m/2 and y=(b+0)/2=b/2 M(m/2,b/2)
Good luck!!!
X+30+70=180
x+100=180. -100 both sides
x=80
|x=80° |
It’s B if there are straight lines and B is there dot it but did u post the same question two times?
