If ∠1 and ∠2 are complementary angles, then one of them must have a measure greater than 45°.

(b)If ∠1 and ∠2 are complementary angles, then one of them must have a measure greater than 45°.=Counterexample:m∠1=, °m∠2°

True or False - Two angles can be Vertical and Complementary

In △𝐴𝐵𝐶, 𝐴𝐵=6𝑐𝑚, 𝐴𝐶=12𝑐𝑚, 𝑚∠𝐴=60∘ and  𝐴𝐶― is the longest side. Which of the following statements about the measures of the angles in △𝐴𝐵𝐶 must be true? (Note: 𝑚∠𝑋 denotes the measure of angle X.)

Select all the correct answers.If the measure of angle is 𝜃  is 7⁢𝜋4 , which statements are true? The measure of the reference angle is 60∘ . The measure of the reference angle is 30∘ . sin(𝜃)=-22 The measure of the reference angle is 45∘ . cos(𝜃)=-22 tan(𝜃)=-1
