Two straight lines AB and CD cut each other at O. If ∠BOD = 63°, the ∠BOC =

Two complementary angles are such that two times the measure of one is equal to three times the measure of the other. The measure of the smaller angle is

Two straight lines AB and CD intersect one another at the point O. If ∠AOC+∠COB+∠BOD = 274°, then ∠AOD =

Consider the following statements:

When two straight lines intersect:

(i) 0Adjacent angles are complementary

(ii) Adjacent angles are supplementary.

(iii) Opposite angles are equal.

(iv) Opposite angles are supplementary.

Of these statements

Given ∠POR = 3x and ∠QOR =2x+10°. If ∠POQ is a straight line, then the value of x is
