Answer:
Step-by-step explanation:
Let the third side of the triangle be .
We can apply the cosine rule to find .
We evaluate to obtain;
We take the positive square root of both sides to obtain;
The correct answer is B.
Twenty five
radians = degrees x PI/180
radians = 60 x pi/180 = 1.04719 radians
round answer as needed
if you need it in terms of pi it would be PI/3 radians
-1
Slope= rise/run
Since the line is decreasing, it will be negative.
