The measure of ∠TSV is 123 degrees.
This can be calculated by realizing that the sum of angles at a point is 360 degrees. Therefore, ∠TSV = 360 - ∠TSR - ∠RSV = 360 - 157 - 54 = 149 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. What is the measure of ∠TSV ? (1 point) °
