Answer:
5a
Step-by-step explanation:
Just use the reflexive property / reflexive angles, 5a = x and 4a equals the remaining side.
3π/4 angle is in the second quadrant, so cos (3π/4) is going to be negative.
Reference angle of 3π/4 is (π - 3π/4) = π/4
cos(π/4) = √2/2
cos (3π/4) = - √2/2
Answer is C.
Answer:
-41
Step-by-step explanation:
Use 2 points to find the equation of the line using the 2-point form of the equation of a line. Then we write the equation in the slope-intercept form to find the y-intercept.

We can use points (-36, -117) and (-27, -98), so
x1 = -36
x2 = -27
y1 = -117
y2 = -98




The y-intercept is -41.
