Third angle =180° - (149° + 9°)
= 22°
Thanks me if is correct!
Slope = (y2-y1)/(x2 - x1)
Slope = (6 - 4)/(-4 - 0)
Slope = 2/-4
Slope = - 1/2
Answer:
hmmm ithink 176
Step-by-step explanation:

In the form y = mx + c
First thing's first, we can determine the gradient, m, simply by looking at the points.
The gradient is determined by how much the value of y increments (or decrements) for each increase of 1 on the x axis.
Every time x increases by 1, y decreases by 4, meaning our gradient is -4.
We are also able to determine our constant, c, by seeing where our line will cross the y axis. In this case, there is a point dead-on the y axis at (0, -2), meaning our constant is -2.
With this information, we can put together the linear equation, y = -4x -2.
We know that
and
; to find
we are going to divide
by
:
Since the denoinatorcan't be zero:
We can conclude that the correct answer is
A.
