Answer:
B = 3,025
Step-by-step explanation:
Use the Pythagoras Theorem
[tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]c^{2}[/tex] ( [tex]c^{2}[/tex] is the Hypotenuse angle/ the slanted line of the triangle)
[tex]30^o[/tex] + [tex]b^{2}[/tex] = [tex]25^o[/tex] ( Isolate [tex]b^{2}[/tex])
[tex]b^{2}[/tex] = [tex]25^o[/tex] + [tex]30^o[/tex]
[tex]b^{2}[/tex] = [tex]55^o\\[/tex]
To find what B is:
[tex]\sqrt{55}[/tex] = b
B = 3025
