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 ?

Answer 1

The measure of angle TSV can be calculated by subtracting the measure of angle TSR from the full circle (360 degrees).

∠TSV = 360 - (157 + 54)
∠TSV = 360 - 211
∠TSV = 149 degrees

Therefore, the measure of angle TSV is 149 degrees.
