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!

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2
