## HannaaLovee 2 years ago AC is tangent to circle O at A. If mBY=24 , what is m<YAC? (The figure is not drawn to scale.) A. 132 B. 48 C. 78 D. 156

thank you ! :)

5. HannaaLovee

i looked at it , but its a bit confusing though.

6. HannaaLovee

well after looking at the other problem , that eliminates A and D so its between B and C

so, which one is the true

8. HannaaLovee

im not sure i got 66 when i did what they said so i ave no clue now

9. HannaaLovee

*have

10. HannaaLovee

i believe it is answer choice B

like they said, u have to find the measure of m<YAB first.... then use complement angles property

what's m<YAB ?

13. HannaaLovee

they never did mention anything about YAB only BAC , BAY and YAC

14. HannaaLovee

nevermind blonde moment its 24?

1/2 * 24 = ...

16. HannaaLovee

okay,12

good, now m<YAB+m<YAC=90 degrees (complementary angels) 12 + m<YAC = 90 m<YAC = ...

18. HannaaLovee

ahh.. 78 :)

yeah... :)
