Sagot :

Answer:

A

Step-by-step explanation:

given that ST is a diameter, then

∠ TRV and ∠ SRV are a linear pair and sum to 180° , that is

∠ TRV + ∠ SRV = 180° , then

∠ TRV + 55° = 180° ( subtract 55° from both sides )

∠ TRV = 125°

Answer:

because the ST is diameter

the SRV+VRT will be 180°

as SRV=55

so VRT will be 180-55=125

so ans will be 125
