Answer 1

Answer:

Extend CD to F so formed CFE triangle answer for the given problem is given

Answer 2

Solution :-

Extend a Line F to C. {Refer To Image Attached}.

So, We can say :-

$\rm{\angle \: BAE \: = \angle \: CFE}$

So, If BAE = 105°, Then

$\rm\angle{CFE = 105°}$

As, The Exterior Angles is the sum of opposite interior angles.

We can Use This In The Question.

So, The Equation Formed Is :-

15° + 105° = x°

Add them.

x° = 120°

So, The Answer Is 120°.
