to fin the last angle we have

the sum of all angles of a triangle is 180

then we sum the angles and match to 180


31+31+x=180

simplify


62+x=180

and solve for x


\begin{gathered} x=180-62 \\ x=118 \end{gathered}

we nee the value of the middle

because the point indicated for the angle is only half of this

now


(118)/(2)=59

the missing angle is 59°
