In the figure, the chords XY and ZW are produced to meet at T such that YT = WT, ZYW = 40o and YTW = 30o. What is YXW?
A.
50o
B.
75o
C.
35o
D.
115o
E.
30o
Correct answer is C
< WYT = 180−302
= 1502
= 75o(base angles of isosceles D)
YXW = 75 - 40 = 35o(Exterior angle is equal to sum of interior angles)
