Question

If a= root 3+1 such that angle b =30° and angle a = 105° then find b​

Answer 1

Answer:

Step-by-step explanation:

Let A, B, & C be the 3 angles of a triangle, and a, b, and c the corresponding sides opposite these angles:

A+B+C=180°

A+30+45=180°  

A=180-75=105°

Using Law of Sines

sin A/a=sin C/c

c=(sin C/sin A)*a

c=(sin 45°/sin 105°)*√3+1

c=2
