Question

Convert the following angles in to radian.
ii) 250°
i) 85°
iii) -132°
v) 75°30'
iv) 65°30'
vi) 40°48'​

Answer 1

Answer:

Step-by-step explanation:

Convert the following angles in to radian.

As we know that π = 180°

=>  180°  = π

& 1° = π/180

π = 3.14

ii) 250° = 250 * π/180  =  4.36  radian

i) 85°  = 85 * π/180  = 1.48  radian

iii) -132° = - 132 * π/180  =  -2.3  radian

v) 75°30' = 75.5° = 75.5  * π/180  = 1.317 Radian

iv) 65°30' = 65.5° = 65.5  * π/180  = 1.14 Radian

vi) 40°48'​  = 40.8° = 40.8 * π/180  = 0.71 Radian

Answer 2

Step-by-step explanation:

vi)40°48

1°=60 min

then to convert 40 degree 48'

40°+48

=40+48/60

=40+12/15

=40+0.8

=40.8

convert to radian

=40.8×π/180

=20.4×π/90

=5.1π/22.5

=5.1×10/22.5×10

51π/225 radian.
