Question

What are the indicated measures

Answer 1

4n + 5n + 6 + 8n -12 + 9n +2 = 360 degrees

26n -4 = 360
26n = 364
n = 14 degrees


Angle A = 56
AngleD = 76
Angle C = 100
Angle B = 128
TOTAL = 360

Answer 2

1. Solve for N
Add all terms together and set equal to 360
(4n)+(9n+2)+(8n-12)+(5n+6)=360
26N= 364
N= 14
M<A = 4(14)= 56
2.9(14)+2=128
3. 8(14)-12= 100
4. 76
