LaTeX: \angle∠J and LaTeX: \angle∠K are supplementary angles. If mLaTeX: \angle∠K is 84LaTeX: ^\circ∘, what is the measure of LaTeX: \angle∠J?
Group of answer choices
180-84=96 The first angle is 84. We know that supplementary angles equal 180. Therefore to find the second angle we just have to take away 84 from 180.
