You can trace a right triangle with these features:
- the 6 feet distance represents the horizontal distance from you to the TV, this is the base of the triangle or the adjacent leg
- the 8 feet distance is the vertical distance from the base of the triangle to the TV, this is the height of the triangle or opposite leg.
- the angle theta that you make with the top of your TV is
tan (theta) = opposite leg / adjacent leg = 8/6 =4/3
=> theta = arctan (4/3) = 53.13 degrees.
Answer: 53.103 degrees
You take away $18.25 away from $40 which becomes $21.75. Then you divide $21.75 by $0.34 which is 63.9705882. You have to round this down to get a full number. Answer=63
