Question

Two angles of the isosceles triangle is 56 degree.Find the third angle?​

Answer 1

Answer:

68

Step-by-step explanation:

isosceles triangle so 2 angles are same i.e, 56

so 3rd angle is 180-(56+56) =68

mark me as braileist pls

Answer 2

Answer:

68°

Step-by-step explanation:

Given :

the measure of two angles of an isosceles triangle =56°

let the third angle be taken as 'x'

we know that the sum of the interior and angles of an triangle is 180°.

so by angle sum property:

(56°+56°)+ x = 180°

112°+x=180°

x =180° - 112°

x = 68°

therefore the measure of the third angle of the isosceles triangle is 68°.
