Aherd of 52 horses has 12 white and some black horses. what is the ratio of white to black horses ?

So we have 52 horses. We know that 12 are white, so:

W : B - 12: x, where x is the unknown amount of horses.

52 - the twelve white horses = 40 other horses.

This means that there are 40 black horses, so the ration of W:B is 12:40. We can simplify this ratio.

The highest common factor of both numbers is 4, so the ratio can be divided by four, giving 3:10.

Therefore the ratio is 3:10.

Hope I helped!

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
