Answer:
112 degrees.
Step-by-step explanation:
- as we know that the three set of forces will form a triangle, by using cosine rule, we can find the required angle.
- follow the diagram in the attachment.
- by cosine rule for
,
2*10*8*cos = 
now, dividing both sides by 2*10*8,
cos = -61/160
= 112.4 degrees = 112 ( appox) ( use calculator for this cos inverse function)
Point A on the graph is rational because the square root of 2.25 is 1.5, which is where point A is located, meaning that point A is is representing a rational number.
Answer:
Interpreting as: + 40 = 0

if there's 3 counselors / 45 students.
3 counselors / 45 students = 1 counselor / 15 student

Tanya paints 55 ft^2 / 30mins.
60 mins = 1 hour
60 mins / 30 mins = 2
55 multiplied by 2 = 110
(There were two different people mentioned in the problem)
Tanya, or Angela, paints 110 square feet every hour.
