Answer:
Step-by-step explanation:
rotation
Step-by-step explanation:
Let θ be the angle of depression i.e the angle between the horizontal and the observer's line of sight.
tanθ= (Height of the light house)/(Horizontal distance of ship from the base of light house)
∴tanθ=88/1532=0.0574
∴θ=tan−1(0.0574)=3.290(2dp)
3+-4=-1
3-4=-1
-1=-1
so the answer is:
-1 = -1
