Draw a line WX through R and parallel to \(\overline{PQ}\) and \(\overline{ST}\) as shown in the diagram above X\(\widehat{R}\)Q = P\(\widehat{Q}\)R = 35º X\(\widehat{R}\)Q + X\(\widehat{R}\)S = 65º 35 + x = 65 x = 65 - 35 = 30º R\(\widehat{S}\)T = 30º (Alternative angle) S\(\widehat{T}\)V = 30º (Alternative angle)
