∡1 = ∡2

∡1 + ∡2 = 90°

therefore

∡1 + ∡1 = 90°
2∡1 = 90°    |divide both sides by 2
∡1 = 45°

Answer: ∡1 = 45°.

For this question we know that m∠1 = m∠2 are equal. I have the diagram I believe you're speaking of and it is a right angle. We know that right angles equal 90 degrees so out of your choices it must be 45 because 45+45=90.
