Answer:

B. $m\angle CAD=\frac{m\widehat {CD}-m\widehat {GE}}{2}$ .

Step-by-step explanation:

We have been given an image of a circle. We are asked to find the measure of angle CAD.

We can see that angle CAD is formed by two intersecting secants outside the circle.

Intersecting secants theorem states that when two secants intersects outside a circle, then the measure of angle formed by secants is half the difference of intercepted arcs.

$m\angle CAD=\frac{\text{Larger arc-Smaller arc}}{2}$

$m\angle CAD=\frac{m\widehat {CD}-m\widehat {GE}}{2}$

Therefore, option B is the correct choice.

hjlf

Answer:

z=-24

Step-by-step explanation:

(z-24)/8+2

(z-24)/10

((z-24)/10)10 Multiply both sides by 10

10(z-24) Distribute

10z-240 Divide both sides by 10

z=-24
