Answer:
Inverse property
Step-by-step explanation:
The definition of the inverse property is to add to get a result of zero. Since we are adding the inverse of each term to get a result of zero each time, we are using the inverse property.
Angle a = 60
given that all angles of a triangle added together must equal 180
x = -20
-20+80=60
do it again for the other angle measurement
60+60+40=180
therefore, angle A is 60°
Answer:
Slope: 1/5
Step-by-step explanation:
-1,2
4,3
-1 - 2 = -1
-1 - 4 = -5
-1/-5 = 1/5
