Answer:
∠ QPR = 64.5°
Step-by-step explanation:
The chord- chord angle QPR is half the sum of the arcs intercepted by the angle and its vertical angle, then
∠ QPR = (QR + ST ) =
(98 + 31)° = 0.5 × 129° = 64.5°

Required
Determine the system of equations
The packages are represented as:
The first: 5G + 4S + 2B
The second: 4G + 4S + 4B
The third: 3G + 4S + 6B
Each of the package costs $26.
So, we have:
-- (1)
-- (2)
-- (3)
Divide both sides of (2) by 2
So, the system of equations are:
