Anyone can contribute an answer, even non-tutors.
Please help. I need the steps
RTQ= SQT (Inscribed angles subtended by the same arc are equal.)
SQT=65
(ii)QST=180-STQ-SQT
= 180-90-65
=25
(iii) A tangent to a circle is perpendicular to the radius drawn to the point of tangency
SQU=90
QUS=180-SQY-QST
=180-90-25
=65
(iv) SO=OT (radius of a circle)
OST=OTS
OST and OTS are both 25
SOT=180-25-25
=130
