Answer:
120
Step-by-step explanation:
150x20%=30
150-30= 120
The sum of interior angles of this pentagon is 540 ( 180(5-2)=540)
So it is : 85+120+90+2x-10+180-x=540. ( in case you ask where did I get 180-x , it is bc the line is 180 degree so minus x it will help us find one of the interior angles)
So x+465=540. x=75
The value of exterior is 75
