Answer:
- 29
- 6
Step-by-step explanation:
<h3>Question 1</h3>It is assumed the chords have equal length: PQ = SR
If the vertexes connected with the center, the both chords will form a right triangle, with the hypotenuse being the radius.
<u>Then the radius is found using Pythagorean theorem:</u>
- r =
=
= 29
<u>Use the intersecting secants theorem: and solve for x:</u>
- FS*FT = FP*FQ
- 4(4 + x) = 5(5 + 3)
- 16 + 4x = 40
- 4x = 24
- x = 6
