Solve sin21^circ=55/x

$$\sin 21 ^ { \circ } = \frac { 55 } { x }$$

Solve for x

$$x = \frac{5500000000000000000}{35836794954530027} = 153\frac{16970371956905716}{35836794954530028} \approx 153.473546029$$

Steps for Solving Linear Equation

Evaluate trigonometric functions in the problem

$$0.35836794954530027 = \frac{55}{x}$$

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

$$0.35836794954530027x=55$$

Divide both sides by 0.35836794954530027.

$$x=\frac{55}{0.35836794954530027}$$

Expand \frac{55}{0.35836794954530027} by multiplying both numerator and the denominator by 100000000000000000.

$$x=\frac{5500000000000000000}{35836794954530027}$$
