Inscibed angle in a circle is 1/2 the value of the intercepted arc

 

intercepted arc = 180 degrees

 

sooo   15 a = 180

              a = 12 degrees

Just a slight correction to EP's answer

 

angle MLK intercepts  an arc of 180

 

So    its  measure  = 90

 

So

 

15 a  = 90

 

a = 90  / 15     =  6 

 

 

cool cool cool
