Answer:
(B)
Step-by-step explanation:
Given: It is given that arc AD=130° and arc AB=arc CD=80°.
To find: The measure of ∠APD.
Solution: It is given that arc AD=130°⇒m∠AOD=130° (The measure of the central angel is equal to the intercepted arc)
Also, arc AB=arc CD=80°⇒m∠AOB=m∠DOC=80° (The measure of the central angel is equal to the intercepted arc)
We know that the sum of the central angles is equal to 360°, thus
m∠AOD+m∠AOB+m∠BOC+m∠COD=360°
⇒130°+80°+m∠BOC+80°=360°
⇒290°+m∠BOC=360°
⇒m∠BOC=360°-290°
⇒m∠BOC=70°
Now, since (The measure of the central angel is equal to the intercepted arc), therefore arcBC=70°.
Also, we know that Angle Formed by Two Secants is half of the DIFFERENCE of Intercepted Arcs, therefore
Substituting the values, we get
⇒
⇒
Thus, the measure of ∠APD is 30°.
Hence, option B is correct.

Answer:
1. B
2. B
Step-by-step explanation:
** Attached picture of the situation
The bird caught the fish at point A, flew until B (which is 100 yds away, dropped the fish at C (which is horizontally 50 yards from A).
1.
We want the angle that the bird creates with the water (horizontal). It is angle BAC. With respect to the right triangle, we can say that we know "hypotenuse" and "adjacent" side to angle BAC. cosine relates hypotenuse and adjacent, thus we can write:
correct answer is B
2.
Here, we want to find the distance (length) of segment BC. With respect to the angle BAC (we found to be 60), we can say BC is "opposite". We know hypotenuse to be 100. So let's use sine, since sine is ratio of opposite to hypotenuse. Thus, we can write:
correct answer is B
The answers should be B)60 and B) 86.6
