Using (n-2)180 to find total number of degrees in a 5-sided shape
n= number of sides

(5-2)180=540degrees

So to find x, 100+160+80= 340
540-340=200

So 8x+8+5x+10=200 and solve for x

LMNP is rotated 180 degrees clockwise around the origin. What are the coordinates of L?

Alona [7]

$\huge\boxed{L^\prime(0, -1)}$

To rotate a point around the origin by 180 degrees, multiply both parts of the coordinate point by $-1$ . (This means you go from $(x, y)$ to $(-x, -y)$ .)

$L(0, 1)$

$L^\prime(0*(-1), 1*(-1))\\\boxed{L^\prime(0, -1)}$
