What is PA Enter your answer in the box

SSSSS [86.1K]

Answer:

Step-by-step explanation:

P is the in-center

⇒PA=PE=PD because they are in-radius of the in-circle

We know that, tangent segments drawn from a point outside the circle are always equal in length

⇒DK=EK=7.2

In right triangle PKE,

using Pythagoras' Theorem : $PK^{2}=PE^{2}+KE^{2}$

⇒ $PE^{2}=PK^{2}-KE^{2}$

⇒ $PE=\sqrt{PK^{2}-KE^{2} }$

⇒ $PE^{2}=\sqrt{7.8^{2}-7.2^{2}} }$

⇒ $PE=3$

Therefore, $PA=3$

An angle of 90° measures (___) Pi radians. An angle of -pi/5 radians measures ____? °.

a_sh-v [17]

$\huge \bf༆ Answer ༄$

Conversion from degree to radian ~

$\boxed{ \sf{ \frac{\pi}{180} \times \theta }}$

$\sf \dfrac{\pi}{180 } \times 90$

$\sf \dfrac{\pi}{2} \: \: rad$

Conversion from radians to degree ~

$\boxed{ \sf{ \frac{180}{\pi} \times \theta}}$

$\sf \dfrac{180}{\pi} \times - \dfrac{ \pi}{5}$

$\sf - 36 \degree$
