Answer:17
Step-by-step explanation:
Answer:
a) 160°
b) 18 sides
Step-by-step explanation:
Interior angle = 180 - exterior
= 180 - 20 = 160°
Each angle of a regular polygon:
[(n-2)×180]/n = 160
180n - 360 = 160n
20n = 360
n = 18
Alternate approach for no. of sides:
360/n = each exterior angle
360/n = 20
n = 360/20 = 18
The answer is going to be 1 and -4 as the 2s cross divide out
Answer:
a) Let Kim's age be k, then Kim's sister's age is k/2
