You would multiply 4 by 72 then u multiply 4 * -6 then after that you would add 15
Answer:
52feet
Step-by-step explanation:
The set up will be a right angle
Let the angle of depression be 30°
The height above the sea level will be the opposite
The distance of the ship from the base is x (adjacent)
Using TOA
Tan theta = opposite/adjacent
Tan 30 = 30/x
x = 30/tan 30
x = 30/0.5774
x = 51.96
x ≈ 52 feet to the nearest foot
Answer:
139.23
Step-by-step explanation:
Let the full marks = x
Then, it would be: x*40/100 = 60
x = 6000/40
x = 150
Full marks will be 150
Answer:
b
Step-by-step explanation:
all you do is divide 10.2 by tan (67) and you get 4.33
