Answer :

The two given angles are (2x + 15)° and (3x-10)°.

We know that vertically opposite angles are equal.


The angle which is vertically opposite to (2x + 15)° is also


corresponding to (3x-10)°.


For l m, the corresponding angles must be equal.


(2x + 15)° and (3x-10)° are both equal to the same angle.


According to the given condition,


(2x + 15)° = (3x-10)°


2x + 15 = 3x – 10


2x – 3x = -10 – 15 (Transposing 3x to LHS and 15 to


RHS)


-x = -25


x = 25 (Multiplying by -1 throughout)


The value of x so that l m is 25°.
