Answer:
y = 6
Step-by-step explanation:
Formula
Chords intersect in such a way that QU * SU = RU * TU
Givens
- QU = 8
- SU = y
- RU = 12
- TU = 4
Solution
- 8 * y = 12 * 4
- 8y = 48
- 8y/8 = 48/8
- y = 6
Plot the points you found in part (b) on a suitable set of coordinates and draw a line through them. It might help your accuracy to use the y-intercept of 20 also.
