26. let s be the set of positive integers defined by to 913 basis step: 1e s recursive step: if n e s, then 3n+2 e s and n2 e s. a) show that if n e s, thenn = 1 (mod 4). b) show that there exists an integer m 1 (mod 4) that does not belong to s

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
