Answer:
Step-by-step explanation:
<em>In a regular pentagon, all the angles and sides are equal. So, to find an angle, divide 540 by 5.</em>
Sum of all angles of regular pentagon = 540
measurement of one angle = 540 ÷ 5
= 108°
∠N = 108°
5/12+5/12=10/12
10/12+10/12=20/12 wich =1.666666666666667theres ur answer to one.
