Answer 1

The angles converted to radian are as follows:

30° = 0.523599 rad

45° = 0.785398 rad

90° =  1.5708 rad

180° =  3.14159 rad

Degree to radian conversion:

• 1 degree = 0.0174533 rad

Therefore,

a.

1° = 0.0174533 rad

30° = ?

cross multiply

angles in radian = 30 × 0.0174533 = 0.523599 rad

b.

1° = 0.0174533 rad

45° = ?

angles in radian = 45 × 0.0174533 = 0.785398 rad

c.

1° = 0.0174533 rad

90° = ?

angles in radian = 90 × 0.0174533 = 1.5708 rad

d.

1° = 0.0174533 rad

180° = ?

angles in radian = 180 × 0.0174533 = 3.14159 rad
