it is a because it is the line is in the spot we're it is ststop to go
I think it’s the second option
Answer:
-3/4
Step-by-step explanation:
Option 1
Direction of the line: Down
-Negative Slope
Rise=-3
Run=4
Rise/Run=-3/4
Option 2
Points: (1,-2) and (-3,1)
y2-y1/x2-x1= 1-(-2)/-3-1
1+2/-3-1
-3/4
You have to find the cos of angle A, so use the Pythagorean equation and trig laws to find the other side of the triangle created by angle A. 3^2 + x^2 = 5^2. x=4. This means cos(A) = 4/5). Make both cos (A) and cos (B) have equal denominators, and add. 148/185 + 60/185 = 208/185. This answer is correct, though it doesn’t appear to be any of the answers you wrote, so either those answers are wrong or you wrote something incorrectly in the problem.
