Question

Please send please answer

Answer 1

as triangle poq and triangle oqr are isoscles triangle oq= op ,oq=or, because op ,oq and or is a radius of a circe

• angle opq = angle oqp = 25 ( opp angle of equal side)
• angle orq = angle oqr = 20
• angle pqr = angle oqp + angle oqr
• = 25+ 20

angle pqr = 45

we also know that the angle subtended by an arc of a circle is double the angle subtended by it at any part on the remaining part of the circle

therefore , 2 angle pqr = angle por

2(45)=angle por

90 =angle por
