Answer:
B. Sometimes
Step-by-step explanation:
Opposite angles of a parallelogram are always congruent, and consecutive angles are always supplementary (first image).
However, consecutive angles can be congruent if they are each 90°. The parallelogram is then a rectangle or a square (second image).
Thus, pairs of consecutive angles of a parallelogram are <u>sometimes</u> congruent.
In order to find the slope, you have to use the formula : Δy/Δx.
Here : Δy = -1 and Δx = 2.
Therefore, the slope would be : B. -1/2.

Answer:
Missing angle = 76 degrees
Informal Argument found below
Step-by-step explanation:
In order to find the missing angle, we would need to add up all of the known angles and subtract them from 180. This is because in every triangle, the angles add up to 180.
Work:
180 = 79 + 25 + x
180 = 104 + x
x = 76
Informal Argument:
The missing angle of the triangle is equal to 76 degrees. This is because all of the angles in a triangle always add up to 180 degrees. When combined with the other two angles, the triangle has a total angle measurement of 180 degrees. Therefore, the missing angle is equal to 76 degrees.
