Answer:
(a) the size of each exterior angle 360/10=36
(b) the number of sides of the polygon. 10
Step-by-step explanation:
Each interior angle of a regular polygon is 4 times each exterior angle
∴sum of interior angles: (n-2)*180=4*360
n-2=8
n=10
(a) the size of each exterior angle 360/10=36
(b) the number of sides of the polygon. 10
Answer:
Step-by-step explanation:
A+B+C = 180°
A ≤ B ≤ C
B = A+9
C = 3A+26
A+B+C = A + (A+9) + (3A+26) = 5A + 35° = 180°
5A = 145°
A = 29°
B = A+9 = 38°
C = 3A+26 = 113°
