I can answer this if the question concerns Penrose tiling using "kite" and "dart" tiles. The "kite" is a quadrilateral whose four corners have angles of 72, 72, 72, and 144 degrees. The "dart" is a non-convex quadrilateral whose four interior angles are 36, 72, 36, and 216 degrees. If however if the questioner want to determine an unknown angle in of a general kite quadrilateral (two sides of length a and two sides of length b, not a parallelogram) when the length of all sides and one angle is known, then the equation [which is too complex for me to easily transcribe] can be found in the Geometry Atlas http://www.geometryatlas.com/entries/153 I can answer this if the question concerns Penrose tiling using "kite" and "dart" tiles.

The angle of a kite is 90degree

There are many different kinds of kites, so likely there is a kite with an acute angle.
A kite is a polygon with four total sides (quadrilateral)
A kite or a trapezium can.
A kite is a quadrilateral having 4 sides and its 4 interior angles add up to 360 degrees
The angle of a kite is 90degree
The angle of attack is the angle that the kite flys into the air at. The angle depends on the wind seeded in the area you are flying the kite in.

A kite (quadrilateral) has a pair of opposite angles which are the same measure. The diagonals are perpendicular, so you can divide the kite into four right triangles, and solve for those if you're given some dimensions. The diagonal, which connects the two congruent (same) angles, will be cut in half (bisected) by the other diagonal.
A kite probably has no right angles.
A kite is a polygon with four total sides (quadrilateral)
right angle triangles have right angles, but there is no such thing as a right angle kite
A kite or a trapezium can.
A certain kite has exactly one acute angle
the measure of an angle is the degrees of an angle.
