To find the measure of angle TSV, we can subtract the angles TSR and VSR from 180 degrees since the three angles TSV, TSR, and VSR form a straight line.
180 degrees - 157 degrees - 54 degrees = 180 degrees - 211 degrees = 31 degrees
Therefore, the measure of angle TSV is 31 degrees.
Use the image to answer the question.
An illustration shows three rays passing through three points from a common origin point at upper S. Point upper T is to the horizontal left of upper S. A ray from upper S joins upper T with an arrow near upper T. Point upper V is on the top inclined to the right of point upper S. A ray from upper S joins upper V with an arrow near upper V. Point upper R is to top right of point upper S, below point upper V. A ray from upper S joins upper R with an arrow near upper R. Angle upper T upper S upper R is labeled as 157 degrees. Angle upper V upper S upper R as 54 degrees.
