Answer 2

Answer:

Original angles= 50° And 30°

They are increased by 5°

New angles= 55° And 35°

TO FIND THIRD ANGLE:

Sum of angles of a triangle= 180°

Let the third angle be x.

⇒ 55°+35°+x°= 180°

⇒ 90°+x°= 180°

⇒ x°= 180°= 90°

⇒ x°= 90°

The third angle is= 90°

The triangle is a right- angled triangle as one of the angles is a right angle i.e. equal to 90°.
