If the measures of five interior angles of a hexagon are each \( 135 ^ \circ\), what is the measure (in degrees) of the remaining interior angle?
What is the measure (in degrees) of \( \angle B + \angle D\) in the diagram below?
What is the measure of \( \angle x + \angle y\) in the diagram below?
What is the measure (in degrees) of \( \angle x\) in the diagram below?
\[\] Details and assumptions:
- If your answer is \(50^\circ \), type it in as \(50\).
If the ratio of the four interior angles of quadrilateral \(ABCD\) in the diagram below is given as \(\angle A : \angle B : \angle C : \angle D = 4 : 2 : 1 : 5 ,\) what is the measure of the biggest angle?
