Question

two angles of a triangle are 60and 80.find the third angle.​

Answer 1

Answer:

60+80+x = 180

180-140 = x

40 = x

Answer 2

Answer:

$\huge\sf\purple{Question}$

two angles of a triangle are 60and 80.find the third angle.

$\huge\sf\purple{Answer}$

$\sf\blue{given}$

• First angle of the triangle = 60°

• Second angle of the triangle = 80°

$\sf\blue{to\:find}$

• Third angle of the triangle = ?

$\huge\sf\pink{Explanation}$

• Let the third angle be x .

By angle sum property of triangle ,

Sum of all angles = 180°

Therefore ,

➡️ 60° + 80° + x = 180°

➡️ 140 + x = 180

➡️ x = 180 - 140

➡️ x = 40°

• Therefore third angle of the triangle is 40°
