Question

Which equation is correct regarding the measure of
<1?
O m_1 = {(a-c)
O mz1 = = {(a + c)
Om 1 =
= {(6-0)
O m_1 = {(b + )

Answer 1

Answer:

m<1 = ½(b - d)

Step-by-step explanation:

Recall: when two secants intersect to form an exterior angle outside a circle, the measure of the exterior angle equals half of the difference of the major and minor arcs intersected.

Thus, in the problem given,

m<1 is the exterior angle

b and d are the arcs intersected.

Therefore,

m<1 = ½(b - d)

Answer 2

The equation that is correct regarding the measure of <1 is; m<1 = ½(b - d)

What is the Secant theorem of a circle?

According to the secant theorem, it states that when two secants intersect to form an exterior angle outside a circle, then the measure of the exterior angle will be equal to half of the difference of the major and minor arcs intersected.

In the given question, we can see that;

The exterior angle = m<1

The arcs intersected are b and d

Thus, from applying the secant theorem, we can express that;

m<1 = ½(b - d)
