Answer 1

180°/15°= π/ x                         180: 15 = 12

180° . x = 15° . π                        15: 15 = 1 nesse caso só o pi

X= 15π / 180

X= π / 12

180°/ π .  2π / 3                                  360 : 3 = 120

180° . 2 / 3 = 360 ° / 3 = 120°

180°/135°= π/x

180° . x = 135° . π

X = 135°π / 180

X = 27°π / 36

X = 3π/ 4

11π/3 . 180° / π

11. 180° / 3= 1980° / 3 = 660°

180°/240°= π / x                   240: 12= 20 : 5 = 4

180° . x = 240 . π                  180 : 12 = 15 : 5 = 3

180°x= 240π

X = 240π / 180°

X= 20π / 15°

X= 4π / 3°
