Measure of angle TRV is [tex]130^{0}[/tex].
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 = [tex]180^{0}[/tex]
(x - 10) + (2x + 10) = [tex]180^{0}[/tex]
3x = [tex]180^{0}[/tex]
x = [tex]\frac{180}{3}[/tex]
x = [tex]60^{0}[/tex]
< TRV = 2x + 10
= 2([tex]60^{0}[/tex])+10
= 120 + 10
= [tex]130^{0}[/tex]
Hence, measure of angle TRV is [tex]130^{0}[/tex].
