Solution Steps

Evaluate trigonometric functions in the problem

$$180 = -2 \cdot 0.01745240643728351 ^ {-1}$$

Calculate 0.01745240643728351 to the power of -1 and get \frac{100000000000000000}{1745240643728351}.

$$180=-2\times \frac{100000000000000000}{1745240643728351}$$

Multiply -2 and \frac{100000000000000000}{1745240643728351} to get -\frac{200000000000000000}{1745240643728351}.

$$180=-\frac{200000000000000000}{1745240643728351}$$

Compare 180 and -\frac{200000000000000000}{1745240643728351}.

$$\text{false}$$
