​

Answer 1

$\bf\red{QuestioN:-}$

To find the unknown marked angles in given figure.

$\bf\green{AnsweR:-}$

Here one angle is given as 50°.

According to the given condition,

➪ The other two angles are equal.

As we know,

Sum of three angles of a triangle = 180

[ Angle sum property of a triangle]

Then,

➪  $\pink\bf{50\°+b\°+b\°=180\°}$

➪ $\pink\bf{2b\°=180\°-50\°}$

➪ $\pink\bf{2b\°=130\°}$

➪   $\pink\bf{b\°=\dfrac{130}{2}}$

➪ $\pink\bf{b\°=75\°}$

•°• The unknown angles are 75° each!
