∠1 and ∠2 form a linear pair. If m∠1 = (5x + 9)° and m∠2 = (3x + 11)°, find the measure of each angle.

• m∠1 = 110° and m∠2 = 70°

• m∠1 = 109° and m∠2 = 71°

• m∠1 = 70° and m∠2 = 110°

• m∠1 = 71° and m∠2 = 109°

If the conditional statement was "If an angle is acute, then it has a measure less than 90°.", which type of statement is the following?

If an angle does not have a measure less than 90°, then it is not acute.

• Contrapositive

• Converse

• Biconditional

• Inverse

If an angle is 40⁰, then it is acute.
