निम्नलिखित रेडियन माप के सांगत डिग्री माप ज्ञात कीजिए ( का प्रयोग करे ):
(i) ` 11/16` (ii) `-4`
(iii) `(5pi)/3` (iv) `(7pi)/6`

Explanation

(i) `C= 11/16`
` :' D = (180^(@)) /pi xx C = (180^(@))/pi xx 11/16 = (180^(@) xx11)/(22/7 xx16)`
` = (180^(@))/22 xx (11xx7)/16 = (315^(@))/8`
`= (39^(@))/8= 39^(@) (3/8 xx 60') = 39^(@)22(1')/2 = 39^(@) 22'30'' `
अतः `11/16 ` रेडियन कि डिग्री माप = `39^(@) 22'30'' `
(ii) ` C = -4`
` :. D = (180^(@))/(22/7) xx C = (180^(@))/(22/7) xx (-4) = (180^(@)xx(-4) xx7)/22`
` = (-2520)/11 = -229^(@) (1/11 xx 60')`
` = -229^(@) (5'(5')/11) = -229^(@)5'(5/11xx60'')`
` = - 229^(@) 5' 27.27'' ` लगभग
` = - 229^(@) 5' 27.3'' ` लगभग
अतः-4 रेडियन कि डिग्री माप `= -229^(@) 5' 27.3'' ` लगभग
(iii) ` C = (5pi)/3`
` :' D = (180^(@))/p xx C = (180^(@))/pi xx (5pi)/3 = 300^(@)`
अतः `(5pi)/6` रेडियन कि डिग्री माप =` 300 ^(@)`
(iv) ` C = (7pi)/6`
` :' D = (180^(@))/pi xx C = (180^(@))/pi xx (7pi)/6 = 210^(@)`
