To solve your question, you add all of the measurements together, set them equal to 180, solve for x, and plug x back in for whichever angle they are asking for; in this case, they want angle R 
7x + 12x + 20 + 20x - 35 = 180
39x - 15 = 180
39x = 180 + 15
39x = 195
x = 5
Angle R = 12x + 20
12(5) + 20
60 + 20
80

Answer:
The question is not complete but from the flow of thought, the question seems to be about what your choice will be between option 1 and option 2.
The correct answer is
option 2
Step-by-step explanation:
The question is asking you to choose an option that pays more after 30 days. In other to determine the more beneficial option, we will compare both options and select the one that pays more. This is done as follows:
option 1: $60,000 per day, after 30 days =
60,000 × 30 = $1,800,000
option 2 = $5,368,709.12 after 30 days
From the total amounts after 30 days of the two options listed above, option 2 is higher than option 1 by $3,568,709. Therefore, option 2 is a better choice.
