Answer:

the answer

Step-by-step explanation:

Hi ,

In a triangle sum of the three angles

is equal to 180°.

In triangle ABC ,

A + B + C = 180° -----( 1 )

A + B = 105

A = 105 - B ----( 2 )

B + C = 120°

C = 120 - B -----( 3 )

Put ( 2 ) and ( 3 ) in equation ( 1 ) ,

105 - B + B + 120 - B = 180

225 - B = 180

- B = 180 - 225

-B = -45

Therefore ,

B = 45°

I hope this helps you.
