Question

In circle P shown the measure of pqrs is 20 degrees what is the measure of p r s

Answer 1

From the properties of circle and chord ,

The angle RSQ is 90 deg.

The angle RQS is 20 deg.

In the triangle , the sum of the angles of the triangle is 180 deg.

`\angle RSQ+\angle RQS+\angle SRQ=180^(\circ)`
`90^(\circ)+20^(\circ)+\angle SRQ=180^(\circ)`
`\angle SRQ=180^(\circ)-110^(\circ)`
`\angle SRQ=70^{\circ^{}}`

The correct option is D.
