cos 4.8 = 36/x

1 answer

To solve the equation \( \cos(4.8) = \frac{36}{x} \), we need to isolate \( x \).

First, we can rewrite the equation as:

\[ x = \frac{36}{\cos(4.8)} \]

Next, we need to calculate \( \cos(4.8) \).

You can use a calculator to find \( \cos(4.8) \):

\[ \cos(4.8) \approx -0.1987 \]

Now substitute this value into the equation:

\[ x = \frac{36}{-0.1987} \]

Now, calculate \( x \):

\[ x \approx \frac{36}{-0.1987} \approx -181.064 \]

So, the solution is approximately:

\[ x \approx -181.064 \]
