Solution:
we are given that
RSTV is an isosceles trapezoid with bases RV and ST and MN || RV.
As we can see from the given diagram the value of angle [tex] <MNV=116^o [/tex]
Since the trapezoid is isosceles so the base angle will be equal.
Hence we can write
[tex] <MNV=<RMN=116^o [/tex]
Since
[tex] <RMN+<SRV=180\\
\\
<SRV=180-116\\
\\
<SRV=64^o\\ [/tex]
