Question

In the diagram of circle A, what is m? 75° 90° 120° 135°

Answer 1

Answer:

Step-by-step explanation:

Answer 2

$90^{\circ}$

Step-by-step explanation:

In the given diagram

Measure of arc=270 degree

Complete angle=360 degree

Measure of other intercepted arc=360-270=90 degree

Angle of intersecting secants  theorem: It states that if two lines are intersecting outside the circle, then the measure of angle formed by the lines is equal to half of the positive difference of the measure of intercepted arcs.

By using this theorem

$\angle M=\frac{1}{2}(270-90)$

$\angle M=\frac{1}{2}(180)=90$

$\angle M=90^{\circ}$

Hence, option B is true.
