Segment Lengths in Circles Find the lengths of segments of chords Find the lengths of segments of tangents and secants
Solve for x x18
EAB C D EA EB = EC ED
E A B C D x 7(7 + 13) 4(4 + x) = Ex: 3 Solve for x. 140 = x 124 = 4x x = 31
E A B C D x 6(6 + 8) 5(5 + x) = Ex: 4 Solve for x. 84 = x 59 = 5x
E A B C EA 2 = EB EC
E A B C x 24 2 =12 (12 + x) 576 = x x = 36 Ex: 5 Solve for x.
E A B C 15 5 x x2x2 =5 (5 + 15) x 2 = 100 x = 10 Ex: 6
