Given that the cosine of an angle is <span>−√3/2, to solve the value of the angle. use the function inverse cosine or arccosine. so the value of the angle
A = arccosine ( </span><span>−√3/2 )
A = 150 degrees
so the answer is D. </span>
<span>150 +n times 360 and 210 +n times 360

Answer:
56 yd²
Step-by-step explanation:
(3 ft)² = 1 yd² = 9 ft²
Multiplying by 56, we find ...
56 yd² = 504 ft²
Answer:
c
Step-by-step explanation:
Answer:
y = x + c.
Step-by-step explanation:
We are given with the line y = 3x + 1 .
Now , we have to find the lines perpendicular to it .
Thus , we have to consider its slope for calculating the slope of required perpendicular lines.
Now, slope of the given line is = 3.
Let the slope of the perpendicular lines be .
Since the two lines of slope and are perpendicular = -1
Thus , = .
So, all lines having the slope are perpendicular to the given line , these lines may be represented by
y = x + c.
