Please Help! AC is tangent to circle O at A. The diagram is not to scale
If mBY = 52, what is mYAC

As shown in picture, AC is tangent to circle O

=> angle BAC = 90 deg

As the property of angle on circle:

=> BAY = (1/2) arc BY = (1/2) x 52 = 26 deg

=> angle YAC = angle BAC - angle BAY = 90 - 26 = 64 deg

Hope this helps!

64°

Step-by-step explanation:

BAC = 90°

BAY = 52/2 = 26°

YAC = 90 - 26 = 64°

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11

these are pretty self explanatory if you know what supp right and com angles are
