Answer: 8 meters per second
Step-by-step explanation:
Hi, to answer this, first, we have to divide the time counted by the number of waves, to obtain the time of each wave:
10 /20 = 0.5 seconds per wave
Now, we simply divide the distance given by the time, to obtain the speed rate:
4/0.5 = 8 meters per second
Feel free to ask for more if needed or if you did not understand something.
To find each of the angles we must make the following clearances:
For ∠A
sin A = 0.96
A = Asin (0.96)
A = 73.7 degrees
For ∠B
tan B = 0.53
B = Atan (0.53)
B = 27.9 degrees
For ∠C
cos C = 0.44
C = Acos (0.44)
C = 63.9 degrees
Answer:
approximate measures of ∠A, ∠B, and ∠C are:
A = 73.7 degrees
B = 27.9 degrees
C = 63.9 degrees
Answer:
Angle CAB=56 degrees
