To find the measure of angle ∠TSV, we can use the information given about the angles around point S.
We know:
- Angle ∠TSR = 157 degrees
- Angle ∠VSR = 54 degrees
The sum of the angles around point S is always 360 degrees. Therefore, we can find the measure of angle ∠TSV using the following relationship:
∠TSV + ∠TSR + ∠VSR = 360 degrees
Plugging in the known values:
∠TSV + 157 degrees + 54 degrees = 360 degrees
Combining the angles:
∠TSV + 211 degrees = 360 degrees
Now, we solve for ∠TSV:
∠TSV = 360 degrees - 211 degrees = 149 degrees
Thus, the measure of ∠TSV is 149 degrees.
