Answer:
C = 79, B = 26 degrees
Step-by-step explanation:
tan C = 5.1323
To find C you use your calculator . Press tan-1 ( or it might be arctan) then the value 5.1323 Then ENTER.
C = 79 degrees to nearest degree.
cos B = 0.8954
B = 26 degrees
Here is your word problem →
A boy had $1.02 with him , his friend Chucky gave him some amount of money and now he has $13.48 . How much money did Chucky gave to that boy.
Solution →
Let the money given by Chucky be c.
Therefore , According to question →
c + 1.02 = 13.48
or, c = 13.48 - 1.02
or, c = 12.46
Answer → Chucky gave him $12.46

Answer:
Step-by-step explanation:
time to cross will be the distance divided by the velocity in that direction.
a) t = d/v = 45/2.75 = 16.363636... 16.4 s
In the same time that the otter is swimming cross stream, the stream is also moving perpendicularly at its own pace.
b) d = vt = 2.5(16.36) = 40.9090... 40.9 m
As velocity is a vector, An observer on the bank would see the velocity as the vector addition of the cross stream and down stream velocities
c) v = √(2.75² + 2.5²) = 3.716517... 3.72 m/s magnitude
θ = arctan2.5/2.75 = 42.2736... 42.3° downstream of a line straight across
