The length of LP is units.

The length of MP is units.

Respuesta :

Answer:

The measure of central angle LOP is °.  180

 

The length of LP is  units.

17

 

The length of MP is  units. 15

Step-by-step explanation:

The measure of  central angle LOP is 56 degrees

The measure of length LP and MP are 17 and 15 respectively

Circle geometry

In order to get the measure of LP and MP, we will use the Pythagoras theorem as shown:

LP = 2OP
LP = 2(8.5)
LP = 17

Determine the length of MP

MP² = LP² - LM²

MP² = 17² - 8²
MP² = 225
MP = 15 units

Using the SOH CAH TOA identity to get the measure of <P
Sin <P = 8/17
<P = 28.07 degrees

The angle at the center = 2(28)

The angle at the center  = 56 degrees

Hene the measure of  central angle LOP is 56 degrees
