A 30 feet wire stretches from the top of a light pole diagonally to the ground the light pole is 10 feet high what is the angle the wire makes with the ground

The wire makes an angle of 19.47 degrees with the ground

Step-by-step explanation:

Here, we want to calculate the value of the angle that the wire makes with the ground

Mathematically, we need an image

From the image, we have a right-angled triangle with the length of the wire as hypotenuse, the height of the pole as opposite

So; we proceed to use a trigonometric identity to get the angle

Mathematically; the trigonometric identity that relates the hypotenuse with the opposite is the sine

So;

sine theta = 10/30

theta = sin^-1 (1/3)

theta = 19.47 degrees

3.0

Step-by-step explanation:

If the ratio is boys to girls, in fraction form (ratio form) that's

When we set up the ratio using the numbers, we have to keep the boy stuff with the boy stuff on top, and the girl stuff with the girl stuff on bottom.  So the ratio with the given numbers is

Reducing that down to decimal form, since 12 is divisible by 4 evenly, would be 3.0
