What is a Circle ?
A circle is a round figure whose all points lie in the same plane.
It is given that
The figure shows a circle with points P, Q, and R on it forming an inscribed triangle, measure of arc QR is 100°,
The measure of an inscribed angle is equal to one-half of the measure of the arc subtended by it,
Therefore
m∠QPR = (1/2) * 100° = 50°.
Angles in triangle
∠ PRQ = 90°
and ∠QPR =20°.
The value of the angle ∠PQR is
By angle sum property
90 +20+ x = 180
110 +x = 180
x = 70
Therefore the value of ∠PQR is 70 degree.
