Answer:
Measure of angle b = 35 degrees
Step-by-step explanation:
180 degrees is the total degrees in a triangle, so you have to do 180-80-65
180-80 = 100
100-65 = 35!
Answer:
810
Step-by-step explanation:

Answer:

Step-by-step explanation:
The slope of a line is always rise over run.
To find the slope of this line, we are looking for two points that are on an integer x value and an integer y value.
One of these points is (-4, 1). Another one is (0, -2).
Studying the y-values of both (the rise), the change in y is
, and since we are going down, the change is
.
Studying the x values of both (the run), we can see that the rate of change is
.
So the rise over run will be
, or just
. This is also the slope as slope is rise over run.
Hope this helped!
