That triangle is isosceles, so the bottom two angles will always be equal. With that said, the equation will be 2(65), and that equals 130. After that, subtract 180-130, and that gives you x! In total, your calculations should look like this:
2(65)
180-130
x=50°

Explanation:


\underline{ \underline{ \text{Given}}} :


  • \angle \: ABC = 65 \degree


\underline{ \underline{ \text{To \: Find}}} :

  • Value of x


\underline{ \underline { \text{Solution}}} :


\angle \: ACB = \angle \: ABC = 65 \degree [ Base angles of isosceles triangle are equal ]


x \degree + 65 \degree + 65 \degree = 180 \degree [ Sum of angle of a triangle ]


x \degree + 130 \degree = 180 \degree


x \degree = 180 \degree - 130 \degree


x = 50 \degree


\red{ \boxed{ \boxed{ \tt{Our \: final \: answer : \boxed{ \underline{ \tt{x = 50 \degree}}}}}}}

Hope I helped ! ♡

Have a wonderful day / night ! ツ
