PO = RO (radius)
there for POR is an isosceles triangle
RPO= 35°
∠ORP+∠RPO+∠POR =180° (angle sum prop)
35°+35°+∠POR =180°
∠POR =180-70
=110°
∠POR+∠ROQ =180° (supplementary angles)
∠ROQ =180-110
=70°

but that is not given
ohhh O is the centre of the circle and a line passing through it and touching 2 points
of the circle is diameter and a diameter is always a straight line
but there is no single line given in the figure
and even if it is done as a construction, how can u determine that points P, O and Q are in a straight line?
It is Diameter
Dont u Know???? Diameter is a Straight Line
i am not telling that. i do know that.
i am asking how can we determine that p, o and q are in a straight line when it is never told in the question nor it is shown in the figure.
nor it is said that poq is the diameter
