Answer:
150°
Step-by-step explanation:
number of terms=12
sum of exterior angles=360
one exterior angle=360/12=30
interior angle=180-30=150°
X + 19 >= 8.2
x >= 8.2 -19
>= -10.8
Answer:
BAC=15
Step-by-step explanation:
angle BOA= 180-30= 150
triangle BAO is
isosceles because it has two equal sides, radii of a circumference so the angles ABO=BAO=(180-150)/2=15
