Step 1: Identify the properties of triangle TSR. Given that |ST| = |SR| and m TSR = 70^, TSR is an isosceles triangle. In an isosceles triangle, the base angles opposite the equal sides are equal. The sum of angles in a triangle is 180^. m STR + m SRT + m TSR = 180^ Since m STR = m SRT: 2 · m SRT + 70^ = 180^ 2 · m SRT = 180^ - 70^
