Solve cos735^circ=1200/x

$$\cos 735 ^ { \circ } = \frac { 1200 } { x }$$

Solve for x

$$x = \frac{800000000000000000}{643950550859379} = 1242\frac{213415832651282}{643950550859379} \approx 1242.331416492$$

Steps for Solving Linear Equation

Evaluate trigonometric functions in the problem

$$0.9659258262890685 = \frac{1200}{x}$$

Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by x.

$$0.9659258262890685x=1200$$

Divide both sides by 0.9659258262890685.

$$x=\frac{1200}{0.9659258262890685}$$

Expand \frac{1200}{0.9659258262890685} by multiplying both numerator and the denominator by 10000000000000000.

$$x=\frac{12000000000000000000}{9659258262890685}$$

Reduce the fraction \frac{12000000000000000000}{9659258262890685} to lowest terms by extracting and canceling out 15.

$$x=\frac{800000000000000000}{643950550859379}$$
