Question

In the given figure, if PT = 2 AP and AB = 18 cm, find PT.
​

Answer 1

Step-by-step explanation:

Fill in the blanks with the participle form of the verbs given in the brackets. 1. I've always wished I could own a ______ (fly) car. The ______ (howl) dog ruined our night. 2. The 3. Rohan's. ____ (bleed) nose meant that he was in a fight. ______ (break) mirror near the doorstep. (interest) show on the National Geographic Channel.

Answer 2

Answer:

BT is diameter and PT is tangent. So, ∠PTB = 90°

In ΔPTB,

⇒ PB^2 = PT^2 + BT^2.

⇒ PB^2 = 72 + 24^2.

⇒ PB = 25cm.

Suppose PA = x

And,

⇒ PT^2 = PA × PB.

⇒ 7^2 = x × 25.

⇒ x = 49/25.

⇒ x = 1.96.

⇒ AB = PB – PA.

⇒ AB = 25 – x = 25 – 1.96.

⇒ AB = 23.04 cm.
