Question

Given: AD diameter of circle P. If m < 1= 30, then m AB=A) 15B) 30C) 60

Answer 1

Answer:

Option B $30\°$

Step-by-step explanation:

we know that

The measure of arc AB is equal to the measure of angle 1 by central angle

so

$arc\ AB=m$ -----> by central angle

we have

$m$

therefore

$arc\ AB=30\°$

Answer 2

The measure of an arc is the size of the corresponding central angle, so angle 1 for AB,

Answer: B
