Step-by-step explanation:
Arrow JK=360-54-130-110=66
arrow MK=66+54=120
Angle L=120/2=60
3a=60
a=30
4 one coefficient and three variables
The answer would be 10 because 9+-5=4+-1=5+5=10
B) C=0.23m+34.99
because you get you base price definitely and extra minute price can be removed if you don't use more than 100
