Question

if the sum of two angles of a triangle is 130degree the third angle of the triangle​

Answer 1

Answer:

50° is the correct answer as sum of an angle is 180°.

if we sub 180-130= 50

pls mark me brainlist

Answer 2

⇝Given :

• Sum of 2 angles of triangle = 130°

⇝To Find :

• Find 3rd angle = ?

⇝Solution :

${\maltese{\underline{\text{As we know that}}}}$

Sum of all angles of triangle = 180°

${\bf{\orange{Let,}}}$

3rd angle = x°

${\maltese{\underline{\text{Solving starts,}}}}$

${\leadsto{\bf{Angle \: 1 + Angle \: 2 + Angle \: 3 = 180°}}}$

${\leadsto{\bf{130° + x° = 180°}}}$

${\leadsto{\bf{X° = 180° - 130°}}}$

${\large{\red{:{\mapsto{\underline{\boxed{\bf{X° = 50°}}}}}}}}$

${\maltese{\underline{\text{So,}}}}$

${\red{\underline{\purple{\underline{\boxed{\bf{3rd \: angle = 50°}}}}}}}$
