We need to convert radian to degree.

1 radian = 57.2958 degrees

a) <span>An angle that measures 2.5 radians is an acute angle. FALSE</span>

2.5 radians = 143.239 degrees.
an acute angle is an angle that is less than 90°. So, 2.5 radians is NOT an acute angle. 

b) <span>An angle that measures 3.5 radians is an obtuse angle. FALSE

An obtuse angle is more than 90</span>° but less than 180°
3.5 radians = 200.535 degrees.

c) An acute angle measures less than 90°. TRUE

d) An angle that measures 285° is a reflex angle. TRUE

A reflex angle is more than 180° but less than 360°
