To get Fractions equal, you can multiply the fraction By any number you want: (a/b) = k.(a/b)
So multiply 3/5 by 3: (3/5).3 = 9/15
Multiply it by 2: 2.(3/5) = 6/10
3/5 = 9/15 = 6/10 = 0.6
Hope this Helps! :)
Answer:
272.17 ft
Step-by-step explanation:
Since the angle of depression of the sighting equals the angle of elevation of the lighthouse from the boat, using trigonometric ratios,
tanθ = x/d where θ = angle of sighting, x = height of lighthouse =55 ft and d = distance of boat from lighthouse at sighting
So, d = x/tanθ
when θ = 8.1°, for the first sighting,
d₁ = 55/tan8.1 = 386.45 ft
when θ = 25.7°, for the second sighting,
d₂ = 55/tan8.1 = 114.28 ft
The distance the boat traveled between the two sightings is thus d₁ - d₂ = 386.45 ft - 114.28 ft = 272.17 ft
Answer:
1
Step-by-step explanation:
Hopefully this is correct. say your starting point is {B} and want to go to {A}. clockwise is always to the left and the mark {B} is on a 90 degree angle both ways. so you would need to go 90 degrees clockwise to get around to A.
I am just a middle schooler hopefully this piece of information may help you figure it out.
The anser is 5162 becuse if you subtract 250 from 1800 it gives you 1550 and then divide 150 by 3
Answer: 21.9
Step-by-step explanation:
-Use Pythagoras theorem-
To find hypotenuse: square root 15 squared plus 16 squared
= 21.9
