Answer:

<ACB = [tex]65^{o}[/tex] and <BAC = [tex]50^{o}[/tex]

Step-by-step explanation:

The given triangle is an isosceles triangle. Thus its two sides are equal and base angles are equal.

So that;

<ACB = <ABC

<ACB = [tex]65^{o}[/tex] (property of an isosceles triangle)

Then,

<ABC + <ACB + <BAC = [tex]180^{o}[/tex]

[tex]65^{o}[/tex] + [tex]65^{o}[/tex] + <BAC = [tex]180^{o}[/tex]

130 + <BAC = [tex]180^{o}[/tex]

<BAC = [tex]180^{o}[/tex] - [tex]130^{o}[/tex]

          = [tex]50^{o}[/tex]

<BAC = [tex]50^{o}[/tex]

Thus, <ACB = [tex]65^{o}[/tex] and <BAC = [tex]50^{o}[/tex].
