a reflection angle is more than
but less than;
an angle that measures
is a reflex angle.(true)
an angle that measures less than
provided we are considering angles greater or equal to zero.

an angle that measures 300° is obtuse (false)
an angle that measures 65° is an acute angle.(true)
3x + 18 = 147°
3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.
