Finding the Angle at the Base of an Isosceles Triangle

To find the angle at the base of an isosceles triangle, we need to know the angle at the vertex of the triangle. In this case, the angle at the vertex is given as 40 degrees.

Let's denote the angle at the base as x.

To find the value of x, we can use the fact that the sum of the angles in a triangle is always 180 degrees.

In an isosceles triangle, the base angles are equal. So, we can set up the following equation:

x + x + 40 = 180

Simplifying the equation, we have:

2x + 40 = 180

Subtracting 40 from both sides, we get:

2x = 140

Dividing both sides by 2, we find:

x = 70

Therefore, the angle at the base of the isosceles triangle is 70 degrees.
