Question

A certain triangle has a 30 angle and a 60 angle.

Answer 1

Correct Question :-

A certain triangle has angles 30° & 60° , then find other angle

Solution :-

Finding othe rangle using angle sum property

Angle sum property :- Sum of all angles in a triangle is always equal to 180°

Let the other angle be x°

So ,

➸ 30° + 60° + x° = 180°

➸ 90° + x° = 180°

➸ x° = 180° - 90°

➸ x° = 90°

Hence, the other angle is 90°
