Question

in the given figure o is the point in interior angle QPR oa is perdendicular to PQ and OT perpendicular to pr if angle qpr is 60°find tos

Answer 1

tos =360-90+90+60=360-240=120

Answer 2

Angle sum of quadrilateral = 360

<PTO+<STP+<PSO+<TOS = 360
90+60+90+<TOS =360
240+<TOS = 360

<TOS = 360-240

= 120°
