I believe the answer to the question is D.
The x-value of a midpoint is the average of the x-values of the ends.
The y-value of a midpoint is the average of the y-values of the ends.
The x-value of the end at b is 20 and it's 18 at the middle.
x has decreased by 2 in the course of 1/2 of the line.
So it will decrease another 2 during the other half of the line.
The x-value at the other end, at a, then, is 16.
The y-value of the end at b is 4 and it's -2 at the middle.
y has decreased by 6 in the course of 1/2 of the line.
So it will decrease another 6 during the other half of the line.
The y-value at the other end, at a, then, is -8.
The other end of the line, at a, is at (16, -8) .
The sum of the coordinates at a (p+q) is 8 .
Answer
A. 84.4
Step-by-step explanation:
The final answer would depend in the type of triangle we are analyzing, however here are the possible outcomes:
1.) If it was a right triangle, 36.5 would be the smaller angle.
2.) It cannot be an equilateral triangle since all angles would be 60°.
3.) In a isosceles triangle, 36.5° would be the smaller, since the others would be 72°.
4.) In an scalene triangle it cannot be determined unless we had 2 angles since in that kind of triangle all angles can be different.
5.) In an acute triangle, 36.5° would be the smaller angle.
6.) In an obtuse triangle it cannot be determined unless we had 2 angles, since it can have highly acute angles.
