Question

please ..........................solve this sum it's very urgent....

Answer 1

x + y = angle RQO
Also, RQO =ORQ ( radii of the same circle are equal and angles opposite to equal sides of a ∆ are equal)
→ x + y =QRO

Now, angle QRS =90(angle in a semicircle)....(1)
and ORP =90 ( radius is perpendicular to tangent)
→angle QRP =angle SRO
→ angle SRO = y

→ angle QRS = x +2y
→ x+2y =90
