We are given that angle C is (9x - 1) degrees, and that this is equal to 64 degrees. Therefore,
9x - 1 = 64
9x = 65
x = 65/9
This means that angle B is (6x + 4) = 6(65/9) + 4 = 47 and 1/3 degrees.
In a cyclic quadrilateral, opposite angles add up to 180 degrees, so angle D + angle B = 180
angle D = 180 - angle B
angle D = 180 - (47 1/3)
angle D = 132 2/3 degrees

That is describing a rectangle! The only quadrilaterals with 4 right angles are squares and rectangles. Squares have equal sides but rectangles have one pair of parallel sides that is longer than the other. Hope this helps!

The length of a rectangle is twice the width. the perimeter is 32 cm more than the width. find the dimensions of the rectangle.
SCORPION-xisa [38]
Width: x
Length: 2x
Perimeter=2x+2x+x+x=6x
32 cm more than width means x+32
6x=x+32
5x=32
x=6.4
Dimension is 6.4×12.8 (width×length)
