The angle sum property of a triangle :

  • The sum of the interior angles of a triangle is 180°.
  • This property of a triangle is true for all triangles.

So ,


\begin{cases}\large\bf\red{ \longrightarrow} \rm \:x \: + \: x \: + \: x \: = \: 180 \degree \\ \\ \large\bf\red{ \longrightarrow} \rm \:3x \: = \: 180 \degree \\ \\ \large\bf\red{ \longrightarrow} \rm \:x \: = \: \cancel(180)/(3) \\ \\ \large\bf\red{ \longrightarrow} \rm \:x \: = \: 60 \degree \end{cases}
