Atriangle rpq is shown. s is a point on side pq and t is a point on side pr. points s and t are joined using a straight line. the length of ps is equal to 3x, the length of sq is equal to 24, the length of pt is equal to 51 and the length of tr is equal to 34.dora is writing statements as shown to prove that if segment st is parallel to segment rq, then x = 12.statement: 1. segment st is parallel to segment qr.2. angle qrt is congruent to angle stp.3. angle spt is congruent to angle qpr.4. triangle spt is similar to triangle qpr.5. (3x + 24): 3x =reason: 1. given.2. corresponding angles formed by parallel lines and their transversal are congruent.3. reflexive property of angles.4. angle-angle similarity postulate.5. corresponding sides of similar triangles are in proportion. which of the following can she use to complete statement 5? a. 85: 51b. 3x: 85c. 3x: 51d. 34: 24
