Measure of angle TRV is \(130^{0}\).
What is an angle?
An angle is formed when two straight lines or rays meet at a common endpoint. The common point of contact is called the vertex of an angle.
According to the question
< TRS + < TRV = \(180^{0}\)
(x - 10) + (2x + 10) = \(180^{0}\)
3x = \(180^{0}\)
x = \(\frac{180}{3}\)
x = \(60^{0}\)
< TRV = 2x + 10
= 2(\(60^{0}\))+10
= 120 + 10
= \(130^{0}\)
Hence, measure of angle TRV is \(130^{0}\).
