Let `z_(1)= cos 12^(@) + I sin 12^(@) and z_(2) = cos 48^(@) + i. sin 48^(@)`. Write complex number `(z_(1) + z_(2))` in polar form. Find its modulus and argument.

Explanation

To solve the problem, we need to find the sum of the complex numbers \( z_1 \) and \( z_2 \), express it in polar form, and then find its modulus and argument.

### Step 1: Write down the complex numbers
Given:
\[ z_1 = \cos 12^\circ + i \sin 12^\circ \]
\[
