Use the image to answer the question.

An illustration shows three rays from a common vertex with labeled angles. The first ray is inclined to the horizontal left of the common vertex with an arrow at the end. The second ray is inclined to the horizontal right of the common vertex with an arrow at the end. The third ray is to the top right of the common vertex with an arrow at the end. It is between the other two rays. The angle between the first and the third rays is labeled as left parenthesis 5 x minus 25 right parenthesis degrees. The angle between the second and third rays as labeled as 55 degrees.

Write an equation for the two adjacent angles.

To formulate the equation for the two adjacent angles, we need to identify the angles first.

  1. The angle between the first ray (left inclined) and the third ray (top right) is given as \((5x - 25)^\circ\).
  2. The angle between the second ray (right inclined) and the third ray is given as \(55^\circ\).

Since these two angles are adjacent and form a straight line, they can be expressed as:

\[ (5x - 25) + 55 = 180 \]

Thus, the final equation representing the adjacent angles is:

\[ (5x - 25) + 55 = 180 \]

You can write it in the requested format:

\[ (5x - 25)° + 55° = 180° \]
