A child in danger of drowning in a river is being carried downstream by a current that has a speed of 2.35km/h. The child is 0.505km from shore and 0.780km upstream of a boat landing when a rescue boat sets out. If the boat proceeds at its maximum speed of 18.8km/h relative to the water,

a) what heading relative to the shore should the captain take?

b)What angle (in degrees) does the boat velocity make with the shore?

2. Relevant equations

3. The attempt at a solution

for a) i just tried using the inverse of tan of (0.6/0.8) but apparently its not right

for b) I thought if the angle found in a was right, i could find the velocity components and subtract the velocity of the river from the y-direction and put those values into a right angled triangle to solve for the angle but that didnt work either
