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.
Either a reflection across the origin. Or a 180° clockwise rotation.
X= -1/3 or as an alternative form x=-0.3 and x=-3 exponent minus 1
What-? this makes no sense but if it’s
3 • 4 + 10 • 10 = 112
34 + 10 • 10 = 134
34 + 1010 = 1044
-5n-8(1+7n)=8
Let's simplify everything.
-5n-8-56n=8
Put the variables on one side and the numbers on the other.
-5n-56n=8+8
Combine like terms.
-61n=16
n=-16/61
Hope I helped! :)
