Question

The angles ot a pentagon are *,(*+20), (x + 40°), (x +60°) and (x +80°). The smallest
angle of the pentagon is: ​

Answer 1

Answer:

68°

Step-by-step explanation:

The sum of all angles of a pentagon is 540°.

=> x+x+20+x+40+x+60+x+80 = 540°

=> 5x+200 = 540°

=> 5x = 540°-200°

=> 5x = 340°

=> x = 340/5

=> x = 68°

Hence, the smallest angle is 68°.

Answer 2

68° is the right answer
