4 0

Step-by-step explanation:

sin (A + B) = 1 =sin 90

A+B=90 equation 1

cos (A - B) = 1=cos 0

A-B=0 equation 2

add 1 and 2

2A=90 A=45

The formula below gives the sum of the degrees, S, of the interior angles of a polygon. If n represents the number of sides, whi
Helga [31]

Answer:

The equation representing the value of <em>n</em> is, n=\frac{S}{180^{\text{o}}}+2.

Step-by-step explanation:

The formula to compute the sum of the degrees, S, of the interior angles of a polygon is:

S=(n-2)\times 180^{\text{o}}

Compute the equation of <em>n</em> as follows:

   S=(n-2)\times 180^{\text{o}}

\frac{S}{180^{\text{o}}}=(n-2)

   n=\frac{S}{180^{\text{o}}}+2

Thus, the equation representing the value of <em>n</em> is, n=\frac{S}{180^{\text{o}}}+2.
