Solve A=-5*45*45*(141-sin(141))_{(1)}

$$A = - 5 \times 45 \times 45 \times ( 141 - \sin ( 141 ) ) _ { ( 1 ) }$$

Solve for A

$$A=-1421253.1310406203932875$$

Steps for Solving Linear Equation

Evaluate trigonometric functions in the problem

$$A = -5 \cdot 45 \cdot 45 \cdot {(141 - 0.6293203910498377)}$$

Multiply -5 and 45 to get -225.

$$A=-225\times 45\left(141-0.6293203910498377\right)$$

Multiply -225 and 45 to get -10125.

$$A=-10125\left(141-0.6293203910498377\right)$$

Subtract 0.6293203910498377 from 141 to get 140.3706796089501623.

$$A=-10125\times 140.3706796089501623$$

Multiply -10125 and 140.3706796089501623 to get -1421253.1310406203932875.

$$A=-1421253.1310406203932875$$

Assign A

$$A≔-1421253.1310406203932875$$
