Question

If PA= 6 and PE =4 find BE

Answer 1

oy ..... chords and tangents eh; you never really use this stuff much afterwards :)

gonna have to look up the "trms"

Answer 2

tan^2 = sec (outer part) ... or some such

Answer 3

in this case:

6^2 = PE(PE+BE)

36 = 4(4 + BE)

36 = 16 + 4BE

36 - 16 = 4BE

36/4 - 16/4 = BE

9 - 4 = 5
