Vertical angle of isoceles triangle = 86 degree
Let one of the base angles be x. ....(i)
We know that, base angles of an isoceles triangle are equal. ....(ii)
We also know, sum of all angles of a triangle =180 degree ....(iii)
....from (i), (ii) and (iii)
x+x+86= 180
2x+86=180
2x= 180-86
2x=94
x= 94/2
x=47
therefore, the base angle is 47 degree.
....hope this answer helps :)
