Question

find x in the given figure​

Answer 1

Since there are 5 sides in a pentagon, substitute the side length . Divide this by 5 to determine the value of each angle, and then multiply by 2 to determine the sum of 2 interior angles.

Answer 2

Answer:

X=108°

Step-by-step explanation:

let one angle be y

All the angles of pentagon are equal

5y=360

y=360/5

y=72

angle y + angle X= 180°. {linear pair}

72 + angle X=180

angle X=180-72

angle X=108°. (option B)
