In an isosceles triangle, the vertex angle is 50:What are the base angle of the angle of thetriangle?​

Answer»

Answer:

65°

Step-by-step explanation:

As we know that the base angle of an ISOSCELES TRIANGLE are ALWAYS equal and sum of INTERIOR angles of a triangle is 180°.

Let the base angles of the isosceles triangle be x° each.

∴x+x+50°=180°

⇒2x=180°−50°

⇒x=

2

130°

=65°

Hence the base angles will be of 65° each.
