Have you learned about the Pythagorean theorem? a² + b² = c² . . . you should teach them about this.
Using the midpoint formula, the coordinates of Q are: <em>A. (-10, 1)</em>
<h3>What is the Midpoint Formula?</h3>
- Midpoint formula is given as,

Thus, given that:
- M is the midpoint of PQ.
- M (-4, 7)
- P (2, 13).
Therefore:

Solve for x-coordinate of P:
-4 = 1/2(2 + x1)
2(-4) = 2 + x1
-8 = 2 + x1
-8 - 2 = x1
x1 = -10
Solve for y-coordinate of P:
7 = 1/2(13 + y1)
14 = 13 + y1
y1 = 1
Therefore, using the midpoint formula, the coordinates of Q are: <em>A. (-10, 1)</em>

Answer:
BC=23
Step-by-step explanation:
Use sine rule:
x/sinX=y/sinY
BC/sinA=AB/sinC
BC/sin61=9/sin20
BC=26.3142396015*sin61
BC=23.0149525338
Answer:
D. c/6 - x
Step-by-step explanation:
Rearranging with subject '6y':
6y = c - 6x
Dividing the above equation by 6 to get subject 'y':
y = c/6 - x
