How do you solve the triangle if A= 50 degrees, B=65, a=10?

Explanation:

In a triangle the sum of all angles equals to 180 degrees.Hence let C be the third angle we have that

#A+B+C=180=>C=180-A-B=>C=180-50-65=65^o#

Now that we know all angles we use the law of sines which states that in a triangle we have that

#sinA/a=sinB/b=sinC/c#

For side b we have that

#sinA/a=sinB/b=>b=sinB/sinA*a=>b=sin65/sin50*10=11.83#

Because #B=C=65^o# this makes the triangle isosceles hence
#b=c=11.83#
