Answer»

Answer:

Given:

One of the equal angles of an ISOSCELES triangle is 50 degree

To Find:

Find all the angles of triangles

Solution:

Let third angle be x

Measure of each of equal angles =50^{\circ}50

∘

Angle sum property: The sum of all angles of triangle is 180°.

Using Property:

So, \begin{gathered}50^{\circ}+50^{\circ}+x=180^{\circ}\\\RIGHTARROW 100^{\circ}+x=180^{\circ}\\\Rightarrow x = 180^{\circ}-100^{\circ}\\\Rightarrow x = 80^{\circ}\END{gathered}

50

∘

+50

∘

+x=180

∘

⇒100

∘

+x=180

∘

⇒x=180

∘

−100

∘

⇒x=80

∘

Hence The angles of triangle are 50°,50° and 80°
