99º, because the sum of all 4 of the interior angles of the parallelogram must be 360º. We know that if one angle measures 81º the other angle on the opposite side must measure 81º.. so 81+81=162
360-162=198
198 - 2(number of remaining angles) = 99º
Answer: 15
Step-by-step explanation:
12.
Start of with simply two times six, which is twelve. Since they're both negatives, they cancel each other out and become positive.
Hope this helps!
keeping in mind that the vertex is half-way between the focus point and the directrix, and since the focus point is above the directrix, meaning the parabola is a vertical parabola opening upwards, the parabola will more or less look like the one in the picture below, with a distance from the vertex of "p" being positive since it's opening upwards.
