12 = A/Cos65
You asked:
Solve the equation \(12 = \frac{A}{\cos\left( 65 \right)}\) for the variable \(A\).
MathBot Answer:
The solution is: \[A = 12 \cos{\left(65 \right)} \approx -6.7494462\]
\[\begin{aligned}12 &= \frac{A}{\cos{\left(65 \right)}}\\A \left(- \frac{1}{\cos{\left(65 \right)}}\right) &= -12\\A &= 12 \cos{\left(65 \right)}\end{aligned}\]
