Answer:

Hope my answer helps you

Step-by-step explanation:So, let’s get started-

In the question, angle c= 105°,

Then, angle B= 45

So, angle a=45° (obviously)

And, AC= 2unit (as you have not provided any specific unit)

So, applying the so called, “Sine Theorem” over here-

sin B/AC = sin C/AB

So, sin 30°/82= sin 45°/AB

Let’s get this quick-

Putting the value of sin 30° and sin 45°,

AB= 2*{(2)^(1/2)} unit

So, AB= 2*1.414 unit

Thus, we arrived at our final result-

AB= 2.828unit (approximately)

or b=2.828unit it’s may be
