*Hint: The Law of Sines is Sin A/a = Sin B/b = Sin C/c
In order to solve this equation, you will have to use this equation:
A= sin^(-1)[a sinB/b]
A= sin^ (-1) [12 (sin 46°) / 11]
A = sin^ (-1) [8.632077604/11]
A = sin ^(-1) [0.7847343276]
A = 51.69611349
Therefore, Sine A would be about 52°
Answer:
Step-by-step explanation:
The total number of marbles is 24 + 36 + 60 = 120
Red: 24/120 = 1/5
Blue: 36/120 = 6/20 = 3/10
Yellow: 60 / 120 = 1/2
Answer: (a) 6760000
(b) 5760000
Step-by-step explanation:
Total letters in English alphabet = 26
Total digits = 10
Given: Each automobile license plate number consists of two letters followed by a four-digit.
(a) If there are no restrictions, then the total number of license plates formed = 26 x 26 x 10 x 10 x 10 x 10
= 6760000
(b) if the letters O and I are not used, total letters can be used ]= 26-2=24
Then the total number of license plates formed = 24 x 24 x 10 x 10 x 10 x 10
=5760000
