Answer 2

well, we know there are 180° in π radians, so. how many radians in -36°?


`\bf \begin{array}{ccll} de grees&radians\\ \text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\ 180&\pi \\ -36&r \end{array}\implies \cfrac{180}{-36}=\cfrac{\pi }{r}\implies r=\cfrac{-36\cdot \pi }{180}`
