Find the angle between →A and →B in degrees.
The supplementary angle of 50∘ is 'a' and the supplementary angle of 110∘ is 'b'.
Find the value of a + b in degrees.
There exist two supplementary angles such that one of them is 30∘ and the other one is two times some arbitrary angle x. Find the value of x (in degrees).
If 'a' and 'b' are two angles of a triangle, then the third angle will be 180 - (a+b) degrees.
