Find the angle measure X in the given figure.​

Answer»

Answer:

X= 108°

Step-by-step EXPLANATION:

ABCDE IS A REGULAR POLYGON

So it's all angles are equal

total sides = 5

sum of angles = (n-2)×180

= (5-2)×180 = 540°

sum of all angles = 540°

/_A +/_B+/_ C +/_ D+ /_ E= 540°

x+x+x+x+x=540

5x=540

x = 108°
