Answer:
7.9km
Step-by-step explanation:
(a)See attached for the diagram representing this situation.
(b)
In Triangle ABC
Next, we determine the value of Angle B.
Finally, we find b.
The distance between the small plane and the observation tower is 7.9km.
Answer:
Step-by-step explanation:
sin(180°-∅)=sin∅ as its in the 2nd quadrant
then tan(180°-∅)= -tan∅ as its in the 2nd quadrant and there only sin and cosec is positive and at last cos(180°-∅) = -cos∅ for the same reason
so by putting the values:
sin∅/sin∅ + -tan∅/tan∅ + -cos∅/cos∅ =1-1-1= -1

We use the definition of the volumes of each figure in order to calculate the diameter of the cylinder. We calculate as follows:
V(cylinder) = V(rectangular prism)
πr²h = lwh
from the given, height of the cylinder = height of the prism
πr² = lw
πr² = 5.3(2.7)
r = 2.13
D=2r = 4.27 mm
