For each of the following, the given angle is the base angle of an
isosceles triangle. Find the third angle of the triangle.
Base Angle
40

Respuesta :

lavya

Answer:

Since it is an isoceles triangle...both the base angles will be equal to 40 degrees

by angle sum property

Third angle + 40+40=180

The third angle will be equal to 100 degrees

Step-by-step explanation:

hope it helps..

Answer:

100

Step-by-step explanation:

We will denote the missing angle as x.

As the base angles of an isosceles triangles are equal, so it would look like this:

x + 40 + 40 = 180

x + 80 = 180

x = 180 - 80

x = 100
