An exterior angle of a regular polygon cannot have the measure Select one: a. 90 b. 120 c. 50 d. 40 e. 30
Otrada [13]

Answer:  c. 50

Step-by-step explanation:

1. By definition, when you add the exterior angles of a regular polygon, you obtain 360 degrees and the number of sides of that polygon can be calculated by dividing 360 degrees by the measure of the exterior angle of it.

2. As you know, the number of sides cannot be fractions, therefore, if you make the folllowing division:

360°/50°=36/5

You obtain a fraction.

3. Then, an exterior angle of a regular polygon cannot have the measure is 50°.

50 POINTS PLEASE SOLVE CORRECTLY!! How do you solve these 2 problems?
Andrew [12]
Ok, so abc is a 3 digit number

easy

if we do
abc=x
then we have
750-x=x
add x to both sides
750=2x
divide both sides by 2
375=x
abc=375

check
750-375=375

correct


abc=375
0.abc=0.375


0.abc=0.375
that was fun
