-1d-7 is the answer I'm pretty sure
Answer:
a) 36°
b ) 18°
Step-by-step explanation:
The formula is given as:
The measure of each exterior angle =360°/n, where n = number of sides of a polygon.
a) decagon
Decagon = 10 sides
Hence, the measure of each exterior angle = 360°/10
= 36°
b) 20-gon
20-gon = 20 sides
Hence, the measure of each exterior angle = 360°/20
= 18°
Answer:
n = 36
Step-by-step explanation:
54 is a midsegment and is one half the measure of the third side, that is
3n = 2 × 54 = 108 ( divide both sides by 3 )
n = 36
