Answer:
170 d.
Step-by-step explanation:
formula for knowing the sum of interior angles of a polygon=(n-2)X180.
sum of interior angles in a Pentagon=(5-2)X180.
= 3X180
= 540.
as all the remaining angles are same we will subtract (150+120)from 540.
= 540-270
=270
now we will divide it by 3 beacuse 3 angles are remaining and all are of same measure.
=270/3
=90.
90 degrees is the answer.
