Answer:
[tex]m\angle Y =120 \degree [/tex]
[tex]m\angle Z =120 \degree [/tex]
Step-by-step explanation:
In quadrilateral TVZY.
TY = VZ (Given)
Therefore,
Quadrilateral TVZY is an isosceles trapezoid.
TV || YZ and VZ is transversal.
[tex]m\angle Z = 180 \degree - 60 \degree \\ (interior \: angles \: on \: same \: side \: \\ of \: transversal) \\ m\angle Z = 120 \degree \\ \\ m\angle Y = m\angle Z \: \\ (base \: angles \: of \: isosceles \: \\ trapezoid) \\ \implies \: m\angle Y =120 \degree [/tex]
