So I know that Angle 1 is 112 degrees and that Angle 3 is 248 degrees.

But I have no idea how to find angle 2. Help me :cry:

Since it's a rhombus both sides would have the same angle vice versa with the other TOP ones

it is not a rhombus

it doesn't have those lines

Angle 1 is 112 degrees because it is double the exterior angle (56 degrees)

Angle 3 is 248 degrees since angle 1 and 3 add up to 360.

Angle 2 is 124 degrees because the opposite angles of a quadrilateral inscribed in a circle are supplementary.

Its not a rhombus. All 4 sides are equal in length in a rhombus.

By "lines", I think that dancanban means those hash marks that show that the sides are congruent.

He means those lines that tells if the side lengths are equal.
