Answer:
C) 75
Step-by-step explanation:
I got this because what you have to do, they all have to add up to 180. so what you do is:
2x + 30 = 180
-30 -30
2x = 150
2x/2 = 150/2
x = 75
Cross-multiplying: 5(b+3) = 14, so 5b + 15 = 14. First answer choice is true.
Answer:
C. 
Step-by-step explanation:
We are given the path,
.
<em>The general form of the straight line is 'y=mx+b', where 'm' is the slope and 'b' is the y-intercept.</em>
Thus, the slope of the given line is -3.
As, we have that the new path is perpendicular to the given path.
And, we know that, 'Product of slopes of perpendicular lines is -1'.
So, we get,

i.e.
.
Since, the new path passes through the point (-3,3). Substituting the values in the general form, we get,

i.e. 
i.e. b= 3+1
i.e. b= 4.
Hence, the equation representing the new path is
.
Thus, option C is correct.
