Solve tan(40)/1=0.77/x

$$\frac{ \tan ( 40 ) }{ 1 } = \frac{ 0.77 }{ x }$$

Solve for x

$$x=\frac{7700000000000000}{8390996311772799}\approx 0.917650266$$

Steps for Solving Linear Equation

Evaluate trigonometric functions in the problem

$$\frac{0.8390996311772799}{1} = \frac{0.77}{x}$$

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

$$x\times 0.8390996311772799=0.77$$

Divide both sides by 0.8390996311772799.

$$x=\frac{0.77}{0.8390996311772799}$$

Expand \frac{0.77}{0.8390996311772799} by multiplying both numerator and the denominator by 10000000000000000.

$$x=\frac{7700000000000000}{8390996311772799}$$
