Question

The angle of a triangle are 45,65, and 70 degree . Express these angles in radians

Answer 1

Answer:

Step-by-step explanation:

To convert into Radian multiply by π/180

(i) 45= 45 × π / 180

= π/4

(ii) 65 = 65 × π / 180

= 13π/36

(iii) 70 = 70 × π/180

= 7π/18

Answer 2

Answer:

45°= (45*π)/180

= {45*22/7}/180

= (990/7)/180

= 141.42/180

= 0.78

65° = (65*π)/180

= (65*22/7)/180

= (1430/7)/180

= 204.28/180

= 1.13

70° = (70*π)180

=(70*22/7)/180

=(1540/7)/180

= 220/180

= 1.22
