Answer:

Step-by-step explanation:

Lets review vector properties:

Let vector A=<a,b> and B=<c,d> and let "c" be a constant, then:

  • cA = c<a,b> = <ca,cb>
  • A+B = <a,b> + <c,d> = <a+c,b+d>

Now, let's do the vector operation shown:

3a-2b\\=3-2\\=+\\=\\=

This is the vector after the operations shown.

A 107-ft-tall building casts a shadow of 90 ft. To the nearest whole degree,
Paul [167]

Answer:

The answer is less than 50 degrees

explanation:

The solar elevation angle is the altitude of the Sun, the angle between the horizon and the centre of the Sun's disc. Since these two angles are complementary, the cosine of either one of them equals the sine of the other. They can both be calculated with the same formula, using results from spherical trigonometry.
