Question

Two angles of a triangle are 30º and 80º. Find the third angle.​

Answer 1

Given:-

• Two angles of a triangle are 30° and 80°

To Find:-

• The Third angle of the triangle

Solution :-

We know that Triangle is a 2D Shape which has three sides and 3 angles.

Angle sum of Triangle = 180

• Let the 3rd angle be x

• 30+80+x = 180°

• 110+x = 180°

• x = 180-110

• The Third Side x = 70

$\bold{ \red{★The \: Third \: Angle = 70}{} }{}$

Verification :-

The Sum of angles of a Triangle = 180°

• 40+80+70 = 180°

• 180° = 180°

Hence Varified The answer..
