Given the triangle RST
As shown:
m∠T = 110
And RT = ST
So, it is an isosceles triangle
so, m∠R = m∠S = x
The sum of the angles of the triangle = 180
So,
[tex]\begin{gathered} m\angle R+m\angle S+m\angle T=180 \\ x+x+110=180 \\ 2x=180-110 \\ 2x=70 \\ x=35 \end{gathered}[/tex]
So, the answer will be:
m∠TRS = 35°
