Answer:
<SRT + <TRV
<VRW + m<WRS
<VRW + m<URS
Explanation:
When two straight lines intersect, the adjacent angles formed on a straight line are referred to as linear pairs and they equal 180°.
The linear pairs from the diagram given are:
<SRT + <TRV
<VRW + m<WRS
<VRW + m<URS
All pairs sum up to 180° each.
