Since M is the midpoint then QM and MR are equal to each other. So by setting them equal to each other we can find the value of x first.
16 + x = 2(x + 2)
16 + x = 2x + 4
16 = x + 4
12 = x
Now we can substitute in the value of x to find the length if QM.
16 + x
16 + 12
28

Answer:
2. it stays the same even if the angles in the triangle change
a. the angles must add up to 180º. a straight line is equal to 180º, so as long as the angles add up to 180º, it will be a straight line.
5. it represents the sum of the measures of the interior angles of the triangle
a. Kellianne lined up the interior angles of the triangle. if added they equal 180º which is the measure of the straight line.
7. it combines the three interior angles of the triangle to form a straight line
a. same answers as previous
8. it is a straight line with a measure of 180º
a. refer to above
hope this helps :)
I think it’s B don’t take me for word.
X - Intercept: 3x + 5y = -15
3x + 5(0) = -15
3x + 0 = -15
3x = -15
3 3
x = -5
(x, y) = (-5, 0)
Y - Intercept: 3x + 5y = -15
3(0) + 5y = -15
0 + 5y = -15
5y = -15
5 5
y = -3
(x, y) = (0, -3)
