Answer:
42°
Step-by-step explanation:
[tex] \triangle ABC\cong\triangle TUV.. (given) [/tex]
[tex] \therefore \angle B\cong\angle U[/tex]
[tex] \therefore m\angle B=m\angle U[/tex]
Therefore,
(2y + 2)° = (3y - 18)°
2y + 2 = 3y - 18
2y - 3y = - 2 - 18
-y = - 20
y = 20
[tex] m\angle U=(3y-18)\degree [/tex]
[tex] m\angle U=(3\times 20-18)\degree [/tex]
[tex] m\angle U=(60-18)\degree [/tex]
[tex] m\angle U=42\degree [/tex]
