Question

In the figure find the value of x. Answer pls ​

Answer 1

Answer:

The angles represented as 3y,4y and 5y at point O, are all made by three lines intersecting each other at point O, which means there are also vertically opposite angles getting formed opposite to the respective angles.

and by the axiom that the total angle at a point is 360°

We get,

2(3y+4y+5y)=360°

Or,

12y= 180°

and hence, y=15°
