Answer:
x=4
Step-by-step explanation:
Pentagon's sum of interior angle is 540°
let's add all the given degrees
100+20x+16x+16+140+160-5x=540
Collect like terms
100+16+140+160+20x+16x-5x=540
416+31x=540
31x=540-416
31x=124
x=124/31
x=4```
M=(y2-y1)/(x2-x1)
m=(-4-4)/(3-1)
m=-8/2
m=-4
so the answer should be first one
