Question

in the figure o is the centre. if qor is 100 degree find qpr and qsr​

Answer 1

Answer:

qpr = 50°

qsr = 130°

Explanation

qpr = 100/2 ( angle subtended at the centre is twice the angle subtended at the circumference)

qpr = 50

qsr = (360 - 100)/2 ( 360 - 100 because we need find the other angle)

= 260/2

= 130

Answer 2

< QPR = 50 ( <QOR/2 OR INSCRIBED ANGLE IS HALF OF CENTRAL ANGLE)

<QSR = <QOR(REFLEX)/2 (INSCRIBED ANGLE IS HALF OF CENTRAL ANGLE)

=260/2

=130
