Question

one angle of triangle abc is 50 degree and the other two angles are equal. find the measure of other two angles​

Answer 1

Given :

• 1st angle of Triangle = 50°
• Other two angles are equal .

To Find :

• Measure of the two angles = ?

SolutioN :

~ We Know That :

• ${\underline{\boxed{\pmb{\sf{ Sum \; of \; Angles{\small_{(Triangle)}} = 180° }}}}}$

Here :

• ➳ ∠1 = 50°
• ➳ ∠2 = z°
• ➳ ∠3 = z°

$\\ \qquad{\rule{150pt}{1pt}}$

~ Calculating the Other angles :

${\twoheadrightarrow{\qquad{\sf{ 50° + z° + z° = 180° }}}} \\ \\ \\ \ {\twoheadrightarrow{\qquad{\sf{ 50° + 2z° = 180° }}}} \\ \\ \\ \ {\twoheadrightarrow{\qquad{\sf{ 2z° = 180° - 50° }}}} \\ \\ \\ \ {\twoheadrightarrow{\qquad{\sf{ 2z° = 130° }}}} \\ \\ \\ \ {\twoheadrightarrow{\qquad{\sf{ z = \dfrac{130}{2} }}}} \\ \\ \\ \ {\twoheadrightarrow{\qquad{\sf{ z = \cancel\dfrac{130}{2} }}}} \\ \\ \\ \ {\qquad \; \; {\therefore \; {\underline{\boxed{\red{\pmb{\frak{ z = 65° }}}}}}}}$

$\\ \qquad{\rule{150pt}{1pt}}$

~ Therefore :

❛❛ Other two angles of the Triangle are 65° . ❜❜

$\\ {\underline{\rule{300pt}{9pt}}}$

Answer 2

answer

other two angles are 65°

Step-by-step explanation:

2X+50=180

2X=130

X=65°
