Answer 1

Answer:

42°

Step-by-step explanation:

$\triangle ABC\cong\triangle TUV.. (given)$

$\therefore \angle B\cong\angle U$

$\therefore m\angle B=m\angle U$

Therefore,

(2y + 2)° = (3y - 18)°

2y + 2 = 3y - 18

2y - 3y = - 2 - 18

-y = - 20

y = 20

$m\angle U=(3y-18)\degree$

$m\angle U=(3\times 20-18)\degree$

$m\angle U=(60-18)\degree$

$m\angle U=42\degree$
