The answer is 65 degrees because there are 180 degrees in a triangle and the triangle isosceles and 130 (because 50 degrees minus 180 = 130) divided by 2 is 65. Youre welcome :D
Because of two sides [tex]AC[/tex] and [tex]BC[/tex] are equal, the angles [tex]\angle A[/tex] and [tex]\angle B[/tex] are also equal. We know that sum of angles of the triangle is equal [tex]180^{\circ}[/tex]. Let [tex]x[/tex] represent [tex]\angle B[/tex]. So, to find [tex]\angle B[/tex] we need to solve the equation: [tex]2x+50=180[/tex] [tex]2x=180-50[/tex] [tex]2x=130[/tex] [tex]x=130/2=65[/tex]
