ST parallel to RA and SR is transversal
R+S=180°[ the sum of co interior angles is 180]
50+S=180
S=180-50
= 130°
in a trapezium ,opposite angles are equal
S=A=130°
T=R=130°
R+S=180°[ the sum of co interior angles is 180]
50+S=180
S=180-50
= 130°
in a trapezium ,opposite angles are equal
S=A=130°
T=R=130°

angle A+angle S =180°
A+50=180
A=180-50
A=130
R+T=180
R=180-50
R=130
A+50=180
A=180-50
A=130
R+T=180
R=180-50
R=130
i am not understanding
