Answer:

tridecagon/triskaidecagon

Explanation:

sum of interior angles= <span>180<span>(n−2)</span></span> degrees, n being the number is sides in the polygon.

sum of interior angles= 1980

<span>180<span>(n−2)</span>=1980</span>

divide by 180:

<span>n−2=<span>1980180</span>=11</span>

add 2:

<span>n=11+2=13</span>

If a polygon has 13 sides, it is called a tridecagon or a triskaidecagon.

Fynjy0 [20]

Answer:

C(50;-20)

Step-by-step explanation:

The question is asking for the midpoint of the line.

The triangle is formed by placing a line directly from the y-axis to the x-axis.

The midpoint theorem is[ (x1+x2)/2 ; (y1+y2)/2 ].

your coordinates at A is (0;-40), because the x value is 0 on the line as shown in the diagram above point A.

Your coordinates for B are (100;0)

C[(x1+x2)/2 ; (y1+y2)/2 ]

C [(0+100)/2 ; (-40+0)/2 ]

C[ 100/2 ; -40/2]

C (50 ; -20)
