Respuesta :

Answer:

57°

Step-by-step explanation:

∠QRS = (157 - 43) / 2 = 57°

Answer:

∠ QRS = 55°

Step-by-step explanation:

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

∠ QRS = [tex]\frac{1}{2}[/tex] ( RS - PS) = [tex]\frac{1}{2}[/tex] (157 - 43)° = [tex]\frac{1}{2}[/tex] × 114° = 57°
