Given AB is perpendicular to BC

<ABO= (2x + y)degrees

<OBC= (6x + 8)deg.

<AOB= (23 + 90)deg

<BOC= (4x + 4)degrees

Find <ABO

(don't know how to draw it but a triangle is within a circle. The triangle name is ABC and segment BO goes through the triangle.)

Confusing question.

You say "a triangle is within a circle"

Are the vertices on the triangle ON the circle?

Where does O come in ? Is O the centre of the circle?

also the statement

<AOB= (23 + 90)deg looks like a typo, all the others contain variable names.

no the vertices is on the point. the 0 i in the center of the circle.
