Answer 2

Step-by-step explanation:

From figure:

AB is the diameter.

In ΔAPB,

⇒ ∠BAP + ∠APB + ∠BAP = 180

⇒ ∠BAP + 90 + 30 = 180

⇒ ∠BAP = 60°

Now,

⇒ ∠BAP = ∠APT + ∠PTA

⇒ 60° = 30° + ∠PTA

⇒ ∠PTA = 30°.

∴ PA = PT{Opposite sides to equal angles are equal}

In ΔABP,

⇒ sin ABP = AP/BA

⇒ sin 30° = AT/BA

⇒ 1/2 = AT/BA

⇒ BA : AT = 2 : 1

Hope it helps!
