Answer:
i honestly dont know i just need the point please marke me as brainleist
Step-by-step explanation:
<A =21
<B = 84
<c = 75
<A =x
<B = 4x
<C =5x-30
The sum of A+B+C = 180
x+ 4x + 5x-30 = 180
Combine like terms
10x -30 = 180
Add 30 to each side
10x-30+30 = 180+30
10x = 210
Divide by 10
10x/10 = 210/10
x= 21
Since x =21 we can find the value of the angles
Substituting x into the equations for angles A, B and C
<B = 4x = 4*21 = 84
<C = 5x-30 = 5*21-30 = 105-30 = 75
solution:
= $15 for 3 packages
= 5 packages per dollar (15/3)
p=18
p+12=30
subtract 12 from each side
