Answer:
A
Step-by-step explanation:
Find AB using the Law of Sine:
![\frac{AB}{sin(C)} = \frac{AC}{sin(B)}](https://tex.z-dn.net/?f=%20%5Cfrac%7BAB%7D%7Bsin%28C%29%7D%20%3D%20%5Cfrac%7BAC%7D%7Bsin%28B%29%7D%20)
Thus:
![\frac{AB}{sin(40)} = \frac{47}{sin(103)}](https://tex.z-dn.net/?f=%20%5Cfrac%7BAB%7D%7Bsin%2840%29%7D%20%3D%20%5Cfrac%7B47%7D%7Bsin%28103%29%7D%20)
Multiply both sides by sin(40)
![\frac{AB}{sin(40)}*sin(40) = \frac{47}{sin(103)}*sin(40)](https://tex.z-dn.net/?f=%20%5Cfrac%7BAB%7D%7Bsin%2840%29%7D%2Asin%2840%29%20%3D%20%5Cfrac%7B47%7D%7Bsin%28103%29%7D%2Asin%2840%29%20)
![AB = \frac{47*Sin(40)}{sin(103)}](https://tex.z-dn.net/?f=%20AB%20%3D%20%5Cfrac%7B47%2ASin%2840%29%7D%7Bsin%28103%29%7D%20)
AB = 31.0056916 ≈ 31.0 cm (nearest tenth)

Answer:
16
Step-by-step explanation:
2 to the power 4
2 × 2 × 2 × 2 = 4 × 2 × 2 = 8 × 2 = 16
Answer: b, d
Step-by-step explanation:
Corresponding angles are formed when two parallel straight lines are cut by a transversal
![\angle b=62^{\circ}](https://tex.z-dn.net/?f=%5Cangle%20b%3D62%5E%7B%5Ccirc%7D)
In the figure,
are alternate angle
![\therefore \angle d=62^{\circ}](https://tex.z-dn.net/?f=%5Ctherefore%20%5Cangle%20d%3D62%5E%7B%5Ccirc%7D)
