There are 4 quadrants in a coordinate plane
- The starting point is in the second quadrant, while the finishing point is in the fourth quadrant.
- The starting point is a reflection of the checkpoint across the y-axis
<u>Part A</u>
The points are given as:
For the starting point, the x-coordinate is negative, while the y-coordinate is positive.
This implies that the starting point is in the second quadrant
For the finishing point, the x-coordinate is positive, while the y-coordinate is negative.
This implies that the finishing point is in the fourth quadrant
<u>Part B</u>
The checking point is given as:
The starting point is given as:
Notice that the y-coordinate of both points are the same, but the x-coordinates are negated.
This means that the starting point is a reflection of the checkpoint across the y-axis, and vice versa

Answer:
c ≈ 40
Step-by-step explanation:
Using the sine ratio in the right triangle
sin40° = =
=
( multiply both sides by c )
c × sin40° = 26 ( divide both sides by sin40° )
c = ≈ 40 ( to the nearest whole number )
