Change both 4 to 2^2 and 8 to 2^3
you now have 2^2(4x-5)=2^3(3x-4)
2(4x-5)=3(3x-4)
8x-10=9x-12
x=2

So there are 52 horses
12 of them are white
how many are black?
52 - 12 = 40
there are 40 black horses
12 white horses to 40 black horses
12:40
12/40

Hope this helps :)

From the top of a tree a bird looks down on a field mouse at an angle of depression of 50 degrees if the field mouse is 40 M fro

Zepler [3.9K]

The tangent function gives the ratio of vertical to horizontal distance in this case.
.. vertical distance = (horizontal distance)*tan(angle of depression)
.. = (40 m)*tan(50°)
.. vertical distance ≈ 47.7 m
