PLEASE HELP ASAP!!!<br><br> Y= [?] degrees
Elis [28]

Answer:

y = 25 degrees

Step-by-step explanation:

We start with 115° and x -

115° + x = 180°

x = 180° - 115°

x = 65°

The sum of all of the angles of a triangle will <em>always</em> be 180 degrees -

x + y + 90° = 180°

We substitute x with 65° -

65° + y + 90° = 180°

y = 180° - 65° - 90°

y = 90° - 65°

y = 25°
