In the figure given below, ∠AOC=67∘, ∠BOC=113∘ and ∠AOB=123∘. Which of the given options is correct?
AOC and AOB are supplementary angles.
AOC and BOC are complementary angles.
AOC and BOC are supplementary angles.
BOC and AOB are complementary angles.
Two angles whose sum is 180∘ are called supplementary angles. So in the given figure the sum of the ∠AOC and ∠BOC = 67∘ + 113∘ = 180∘. Hence, ∠AOC and ∠BOC are supplementary.
In figure, OB⊥OA, ∠AOC and ∠BOC are complementary angles . Find the value of x and hence find ∠AOC and ∠BOC. [3 MARKS]
In figure,∠AOC =50∘and∠BOC = 20∘, find∠AOB.
In the given figure ∠AOC and ∠BOC form a pair of (a) vertically opposite angles (b) complementary angles (c) alternate interior angles (d) supplementary angles
