Use the properties of exterior angles of triangles to find angle b

Answer 1

To find angle b, we need to consider the properties of exterior angles of a triangle.

The exterior angle theorem states that the measure of an exterior angle of a triangle is equal to the sum of the measures of its remote interior angles.

In this case, since angle b is an exterior angle, it is equal to the sum of angles a and c.

Therefore,
angle b = angle a + angle c

However, without specific values for angles a and c, we cannot determine the exact measure of angle b.
