Answer:

PR = 74°

Explanation:

The secant- tangent angle PQR is half the difference of the intercepted arcs, that is


(1)/(2) ( PS - PR ) = 50° (multiply both sides by 2 to clear the fraction )

PS - PR = 100°

174° - PR = 100° ( subtract 174° from both sides )

- PR = - 74° ( multiply both sides by - 1 )

PR = 74°
