Let the number of Payday be p and Baby Ruth be b

Then sub of the candy bars:

p + b = 220

Payday candy bars worth ⇒ $2p
Baby Ruth candy bars worth ⇒ $3b
Total ⇒ $600

1. Required equations:

p + b = 220
2p + 3b = 600

2. Solving by substitution:

p = 220 - b, consider it in the second equation

2(220 - b) + 3b = 600
660 - 2b + 3b = 600
660 + b = 600
b = 660 - 600
b = 60

What is the measure of angle A?

I am Lyosha [343]

First you have to find the angle B (check attachment)

$B = 180^{\circ} - 137^{\circ} = 43^{\circ}\\$

Then you can find the last angle inside the triangle, which I'll call C

$C = 180^{\circ} - 102^{\circ} - 43^{\circ} = 35^{\circ}$

Now you can find angle A

$A = 180^{\circ} - C = 180^{\circ} - 35^{\circ} = 145^{\circ}$
