Algebra Find the value of each variable using the given chord, secant, and tangent lengths. If the answer is not a whole number, round to the nearest tenth.

Answer/Step-by-step explanation:

15. Based on the intersecting Chords Theorem, thus,

Divide both sides by 8

x = 15

17. Based on the two secants intersecting theorem,

Solve for c

Subtract 169 from each side

Divide both sides by 13

c = 13.2 (nearest tenth)

19. ✔️Based on the two secants intersecting theorem,

Solve for x

Subtract 25 from each side

Divide both sides by 5

x = 25.8

✔️according to the tangent and secant theorem, thus:

Solve for y

Square both sides

y = 12.4 (nearest tenth)
