Answer:

To find the angle RST we have to first find SRT As the exterior angle adjoined with SRT =53°

so the SRT = Outer angle adjoined with angle SRT

angle SRT = 53° [°.° vertically opposite angles are equal]

Angle SRT + Angle STR + Angle RST = 180°

=>53° + 75° + Angle RST =180°

=> 128° + Angle RST = 180°

=> Angle RST =(180-128)°

= 52°

SO NO. C IS correct what Cate says is absolutely right
