Answer 1

Answer:

1. is ans

Step-by-step explanation:

T is 90°

PC2 =PT2+TC2

PC2=8×8 + 6×6

=64+36 =100

therefore 10 is the root of 100

Answer 2

$\huge{\underline{\underline{\boxed{\sf{\purple{Gɪᴠᴇɴ}}}}}}$

Radius = 6cm

TC = AC = 6 cm

PT = 8 cm

<PTC = 90° (PT is tangent)

$\huge{\underline{\underline{\boxed{\sf{\purple{Tᴏ ғɪɴᴅ}}}}}}$

Distance of the point P from the nearest point of the circumference = PA = ?

In Right ∆PTC,

By using pythegorus theorem :

H² = B² + P²

PC² = TC² + PT²

PC²= 6² + 8²

PC² = 36 + 64

PC² = 100

PC = √100

PC = 10 cm

PA = PC - AC = 10 - 6 = 4 cm

Distance of the point P from the nearest point of the circumference = PA = 4 cm
