  if ∠B is not a right angle, then m∠B ≠ 90°.

Step-by-step explanation:

The contrapositive of ...

  If P, then Q.

is ...

  If not Q, then not P.

__

Here, we have ...

  P = m∠B = 90°   ⇒   not P = m∠B ≠ 90°

  Q = ∠B is a right angle   ⇒   not Q = ∠B is not a right angle

Then the contrapositive is ...

  If ∠B is not a right angle, then m∠B ≠ 90°.
