The problem in the image shows a triangle with three angle expressions involving \(z\) and \(c\). The interior angles of any triangle sum to 180°. Let's analyze the angles provided in the image.

The angles are:
1. \( 2z \) (bottom left angle)
2. \( 8z - 31^\circ \) (top angle)
3. \( 25c - 26^\circ \) and \( 11z - 47^\circ \) (bottom right angle, exterior)

For the internal angles of a triangle:
- The sum of the internal angles should equal 180°.
- Using this, we can solve for \( z \), since there are two expressions involving \(z\), but one exterior angle, which also uses \( z \).

I will now calculate \(z\), assuming we focus on expressions directly related to \( z \) and the interior angles. Please confirm if the variable \( c \) is needed for calculation or if it's meant to focus just on \(z\).

What is the value of z in the triangle, given the angles: 2z, 8z - 31°, 25c - 26° and 11z - 47°?

Find the value of z by using the sum of angles in a triangle and the exterior angle theorem. This problem includes algebraic expressions and is suitable for students in Grades 9-11.
