Find the value of xxx.
Which of the following pair(s) is/are complementary angles?
If ∠AOB=−9x+29\angle AOB=-9x+29∠AOB=−9x+29 and ∠BOC=2x+82\angle BOC=2x+82∠BOC=2x+82, find the value of xxx.
Use the idea of supplementary angles to prove for vertical angles.
Given that ∠m=\angle m=∠m=43°, find the remaining angles in the diagram.
Given that ∠AOC\angle AOC∠AOC=125° and ∠DOE\angle DOE∠DOE=35°.
If ∠AOD\angle AOD∠AOD=3x+14 and ∠BOC\angle BOC∠BOC=7x-18, find the value of x.
What of the following is/are adjacent angles?
∠AOB\angle AOB∠AOB=30°, ∠AOC\angle AOC∠AOC=100°.
