A:

Answer:1. x=160 (here given as ques no. 5)2. x=81 (here given as ques no.5)4. No (here given as ques no. 8)Step-by-step explanation:1. Given ∠STR=∠SRT=20° we know ∠STR+∠STU=180 x+20=180 x=1602. By external angle property x+24=105 x=813. By Angle Sum Property∠ 1=∠2=∠3=∠4=90and∠5=∠6=∠7=∠8=90Hence all angles are equal to 90and we know only parallel lines have∠4=∠5∠3=∠6hence line 'r' and line 't' are parallel.4. For being parallel side pieces must not form a triangle(i.e. sum two interior angle must be equal to 180)But here sum of interior angle 174 Hence a triangle is possible.So , lines are not possible .
