Answer:
35
Step-by-step explanation:
A triangle has a total of 180 degrees. To find the missing angle, we subtract 113 and 32 from 180 to get the answer.
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)
You just add up all of the x times by 457, since you combine like terms.
