Answer:

Step-by-step explanation:

apply sine rule 2 the triangle on left:

sinB'/10=sin45deg/8.2

sinB'=10*sin45deg/8.2=0.8623

B'=59.58deg or 120.42deg

as shown in the pic, B' > 90deg.

so B'=120.42deg.

the triangle on right has 2 sides at 8.2 so it is isosceles

B=adjacent < of B'

=180-120.42

=59.58deg
