If m∠1 = m∠2, then m∠1 is 30 45 60 90
∡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.
