Question

angles. 10. If two angles x and y are adjacent, state if their exterior arms are in a straight line when (i) x = 110° and y = 60°, (ii) x = 102, y = 78°.
Slove this and please give fully explanation please ​

Answer 1

Answer:

Ans:- (ii)x=102,y=78

Step-by-step explanation:

Given, x,y are adjecent angles ,exterior arms are in straight line so, we needa pair of supplementary angles .because x ,y are angles in linear pair

102 & 72 is a pair of supplementory angle
