$\\ \rm\longmapsto n-2(180)=165n$

$\\ \rm\longmapsto 180n-360=165n$

$\\ \rm\longmapsto 15n=360$

$\\ \rm\longmapsto n=360/15$

$\\ \rm\longmapsto n=24$

n is no of sides

The graph of the function B is shown below. If B(x) = -1, then what is x?

Harlamova29_29 [7]

x = 2, that is B(2) = - 1

From the coordinate diagram, the value of x ( x- axis ) corresponding to the value of y = -1 ( y- axis ) is x = 2

That is the point (2, - 1 )

Three students attempt to define what it means for lines lll and mmm to be perpendicular.

Vanyuwa [196]

Please find diagram attached

Answer and explanation:

Perpendicular lines are lines that meet at 90 degrees/ right angle.

The question seems to be incomplete but I will explain what perpendicular lines are in the context of lines lll and mmm, with some assumptions about the lines.

Assume that line III is 30mm long and line mmm is 25mm long, we say that line III is perpendicular to line mmm if line III meets line mmm at 90 degrees as we see in the diagram attached.
