Use the image to answer the question.
An illustration shows three rays A, D, and C emerging from a point labeled B, forming a right angle at B. The right angle is divided into two parts by ray B D. The angles face leftward. Angle A B C measures 90 degree, angle A B D measures 4 x degrees, and angle D B C measures left parenthesis 7 x minus 9 right parenthesis degrees.

The equation for determining the angle measures is:
90° + 4x° + (7x - 9)° = 0
wrong
I apologize for the mistake. Let me correct it.
The equation for determining the angle measures is:
90° + 4x° + (7x - 9)° = 180°
