Alawn mower uses 0.7 gallons of gas every 3 hours. the gas tank holds 2 gallons. how long can the mower run on a full tank?

Option D. 36°

Step-by-step explanation:

we know that

The sum of the exterior angles of a polygon must be equal to 360 degrees

In a regular polygon all the exterior angles are congruent

so

To obtain the measure of each exterior angle divide 360 by the number of sides

In this problem the number of sides is 10

360/10=36°
