Question

From degrees to radians

Find the radian measure of the angle $-{70}^{°}$. Round your answer to three decimal places.

Short answer

Angle in radians is$\mathbf{-}\mathbf{1}\mathbf{.221}$

Step-by-step solution

Step 1. Given information.

An angle of$-{70}^{°}$ and we have to convert it into radians

Step 2. Concept used.

To convert an angle from degrees to radians, then multiply the given angle by $\frac{\pi }{180}$.

The answer will be in radians.

Step 3. Calculation.

Here is the calculation-

$$\begin{gathered} 1^{°}=\frac{\pi }{180} \\ -{70}^{°}=\frac{\pi }{180}\times (-70)\Rightarrow -1.221 \end{gathered}$$
