Answer:
The measure of angle RST is 80
Step-by-step explanation:
Since they are vertical angles, then they must be equal as vertically opposite angles are equal
Thus;
5b + 20 = 7b - 4
7b - 5b = 20 + 4
2b = 24
b = 24/2
b = 12
But RST = 5b + 20
substitute for b
RST = 5(12) + 20
RST = 60 + 20
RST = 80
Answer: If the prices increase 3.7% each month, then they would increase 44.4% in a year.
