Solution Steps

Evaluate trigonometric functions in the problem

$$\left. \begin{array} { l } { z_{1} = 7 \cdot 0.9063077870366499 }\\ { a = 2 \cdot 0.42261826174069944 } \end{array} \right.$$

Consider the first equation. Multiply 7 and 0.9063077870366499 to get 6.3441545092565493.

$$z_{1}=6.3441545092565493$$

Consider the second equation. Multiply 2 and 0.42261826174069944 to get 0.84523652348139888.

$$a=0.84523652348139888$$

The system is now solved.

$$z_{1}=6.3441545092565493 a=0.84523652348139888$$
