Answer 1

☆ Question ☆

Two angles of a traingle are 30 degree and 60 degree. Find the 3rd angle of a traingle.

☆ Solution ☆

Given

• Two angles of a traingle are 30 degree and 60 degree.

To find

• The 3rd angle of a triangle.

Step-by-Step-Explaination

Sum of angles in a triangle = 180°

Given, two angles are 30° and 60°

Let the 3rd angle be x

So,

30° + 60° + x = 180°

90° + x° = 180°

x = 180° - 90°

x = 90°

Hence, the 3rd angle of triangle is 90°.
