d) 215º
e) 330º
f) 32º
g) 87º

URGEEENTE, PF!!!

Answer 1

pi --- 180
 x ---  55 

180x = 55pi
x = 55pi / 180
x = 11/36 pi radiano

pi --- 180
 x ---  72

180x = 72pi
x = 72pi / 180
x = 2/5 pi radiano

pi --- 180
 x ---  195 

180x = 195pi
x = 195pi / 180
x = 13/12 pi radiano

pi --- 180
 x ---  215 

180x = 215pi
x = 215 pi / 180
x = 43/36 pi radiano

pi --- 180
 x ---  330 

180x = 330pi
x = 330 pi / 180
x = 11/6 pi radiano

pi --- 180
 x ---  32

180x = 32pi
x = 32 pi / 180
x = 8/45 pi radiano

pi --- 180
 x ---  87

180x = 87pi
x = 87pi / 180
x = 29/60 pi radiano

BONS ESTUDOS!

Answer 2

a) π ⇒ 180 
   x ⇒ 55 

 180x = 55π
 x = 55π /180
x = 11/36 πrad 

 b)π ⇒ 180 
   x ⇒  72  
180x = 72π
 x = 72π / 180
 x = 2/5 πrad

   c)π ⇒180 
   x ⇒ 195  

180x = 195π
x = 195π/180
x = 13/12 πrad 


 d)π ⇒ 180
 x ⇒ 215  


180x = 215π
 x = 215 π /180
 x = 43/36 πrad

   e)π ⇒ 180 
     x ⇒  330 


 180x = 330π
 x = 330 π/180
x = 11/6 πrad 

f) π ⇒180
 x ⇒ 32 


 180x = 32π
 x = 32 π /180
x = 8/45 πrad

   g) π ⇒180 
     x ⇒ 87

180x = 87π
 x = 87π/180
x = 29/60 πrad
