Jelo, dgenerationx2!
For the first two, we need this theorem:
The angle between a tangent and a secant (to the point of tangency)
. . is one-half the intercepted arc.
1) Given: . . Find:
. .Code:D * * * o * * * o * F * * * * 190° * * * C o * * * * * * 50° * * * * * * * B - - - * o * - - - - E A
Therefore: . . . . answer (A)
Given: .tangent and secant . Find:Code:* * * * * * * C o D o / * / * 200° * / * * / * / * / * * / * * / * * o * - - - - - A B
We hafve: .
Therefore: . . . . answer (A)
