Answer:
14) 21.136505024965 m
15) 43.076759215619 km
Step-by-step explanation:
14)
let h be the height of the lighthouse:
tan(41.3) = 18.7/h
Then
h = 18.7÷tan(41.5)
= 21.136505024965 m
………………………………………
15)
90-71.4 =18.6
Let s be the distance that the plane flew
towards the south:
tan(90 - 71.4) = s/128
Then
tan(18.6) = s/128
Then
s = tan(18.6)×128
= 43.076759215619 km

Answer:
To find the missing base, you simply divided the area by the given height. This will work the same way if you are looking for the height. To find the missing height, divide the area by the given base. Consider this parallelogram where height is the missing dimension.Oct 30, 2012
Step-by-step explanation:
Answer: 68 mL
Step 1: Write volume formula
The formula for volume is often abbreviated into V=l×w×h. This stands for volume= length×width×height.
Step 2: Substitute numbers for answer in cm
To get the answer in cm, simply substitute the numbers into the equation. Then, you may simply multiple them to solve.
V=4.0 cm×8.5 cm×2.0 cm
V= 68 cm
Step 3: Add cubed symbol
Since this is referring to volume, you will need to add the cubed symbol to the end of your answer. This will appear as a number 3 above the cm on the right side.
Step 4: Convert to mL
This is a simple step once you understand the formula to convert. Luckily for us, cm cubed (cm3)= 1 mL. Because of this, the answer will remain as 68 mL
Hope this is right and it helps you!
