it's 90 degrees
360
It is 90 degrees or pi/2 radians.
A chevron (arrowhead) is a quadrilateral with one angle of more than 1800.
The sum of all four interior angles in a quadrilateral must be 360, so the answer would be: 360 - 54 - 25 - 99 = 182
There is no specific limitation on any one angle of an inscribed quadrilateral.
it's 90 degrees
That depends on the quadrilateral. They will not all have the same measure. Even rectangles will not all have the same central angle measures.
A regular quadrilateral is a square. As to the measure, the answer depends on the measure of WHAT? An angle, a side, the diagonal, area, perimeter, etc.

If it's a square then it's 90 degrees
The following are angles in a convex quadrilateral: Angle A = 80 degrees Angle B = 98 degree Angle C = 70 degrees What is the measure of the missing angle?
50 degrees (360 degrees in a quadrilateral)
Each exterior angle of a square is 90 degrees and a square is a regular 4 sided quadrilateral
90 degrees.
