Hello,
Perimeter is a function of the number of hexagons.
Answer: Measure of angle E = 45°
Measure of angle D = 45°+5° = 50°
Measure of angle F = 85°
Step-by-step explanation:
Let the measure of angle E be x. ( in degrees)
Then Measure of angle D = x+5
Also, Angle D + Angle E = Angle F +10

Since DEF is a triangle, so the sum of their angles should equal to 180 degrees.

Measure of angle E = 45°
Measure of angle D = 45°+5° = 50°
Measure of angle F = (2(45)-5)° = (90-5)° = 85°
The answer to this problem is going to be C.
10 would be my best bet. Hope this helps.
