ANSWER
a = 1.554
b = 1.258
![Z_1\text{ = }1.554\text{ + 1.258 i}](https://tex.z-dn.net/?f=Z_1%5Ctext%7B%20%3D%20%7D1.554%5Ctext%7B%20%2B%201.258%20i%7D)
EXPLANATION
Step 1: Given that:
![\text{ The absolute value or the modulus (r) = }|z_1|\text{ = 2}](https://tex.z-dn.net/?f=%5Ctext%7B%20The%20absolute%20value%20or%20the%20modulus%20%28r%29%20%3D%20%7D%7Cz_1%7C%5Ctext%7B%20%3D%202%7D)
![\text{The argument of the complex number (}\theta)=39^0](https://tex.z-dn.net/?f=%5Ctext%7BThe%20argument%20of%20the%20complex%20number%20%28%7D%5Ctheta%29%3D39%5E0)
Step 2: The rectangular form of a complex number is given by:
![Z_1\text{ = a + bi}](https://tex.z-dn.net/?f=Z_1%5Ctext%7B%20%3D%20a%20%2B%20bi%7D)
Step 3: Using basic trigonometric ratios to determine a and b
![\begin{gathered} \sin \text{ 39 = }\frac{b}{2} \\ b\text{ = 2 sin 39 = 1.258} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%5Csin%20%5Ctext%7B%2039%20%3D%20%7D%5Cfrac%7Bb%7D%7B2%7D%20%5C%5C%20b%5Ctext%7B%20%3D%202%20sin%2039%20%3D%201.258%7D%20%5Cend%7Bgathered%7D)
![\begin{gathered} \cos \text{ 39 = }\frac{a}{2} \\ a\text{ = 2 cos 39 = 1.554} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%5Ccos%20%5Ctext%7B%2039%20%3D%20%7D%5Cfrac%7Ba%7D%7B2%7D%20%5C%5C%20a%5Ctext%7B%20%3D%202%20cos%2039%20%3D%201.554%7D%20%5Cend%7Bgathered%7D)
Hence, the rectangular form of the complex number is:
![Z_1\text{ = }1.554\text{ + 1.258i}](https://tex.z-dn.net/?f=Z_1%5Ctext%7B%20%3D%20%7D1.554%5Ctext%7B%20%2B%201.258i%7D)
