$\huge{\bf{\green{\mathfrak{Question:-}}}}$

• Find the third angle of triangle if two angles are 60° and 38°.

------------------------------------------------------------------

$\huge {\bf{\orange{\mathfrak{Answer:-}}}}$

• Let the angles of the triangle be x°, y° and z°.

• $\textsf{One angle = x° = 60°}$

• $\textsf{Second angle = y° = 38°}$

• $\textsf{Third angle = z° = ?}$

• $\boxed{\textsf{x° + y° + z° = 180° ( Angle sum property of a triangle)}}$

• $\textsf{60° + 38° + z° = 180°}$

• $\textsf{98° + z° = 180°}$

• $\textsf{z° = 180° - 98°}$

• $\boxed{\textsf{Third side = z° = 82°}}$

------------------------------------------------------------------

$\huge{\bf{\red{\mathfrak{Conclusion:-}}}}$

• $\boxed{\therefore{\textsf{Third side = 82°}}}$

Answer 2

Given :-

• First Angle of Triangle = 60°
• Second Angle of Triangle = 38°

To Find :-

• Third Angle of Triangle

Solution :-

❏ As we know that, Sum of all the Angles of a Triangle is 180° ( Angle Sum Property of Triangle )

Putting the Values :

➞ ∠1 + ∠2 + ∠3 = 180°

➞ 60 + 38 + ∠3 = 180

➞ 60 + 38 + ∠3 = 180

➞ 98 + ∠3 = 180

➞ ∠3 = 180 - 98

➞ ∠3 = 82°

Thus Third angle of the Triangle is 82°
