Answer:
30 degrees
Step-by-step explanation:
I think that every corner is a 90 degree angle so 90/2 is 30
(i) XYZ = 180 - 64
= 116 degrees
Opposite angles in a cyclic quadrilateral add up to 180 degrees
(ii) YXZ = 23 degrees
Alternate angles in a segment are the same
(iii) OXZ = 26
XOZ = 64 x 2
= 128 degrees
The the angle at the centre is double the angle at the circumference.
180 - 128 = 52
OXZ = 52/2
= 26
Triangle OZX is an isosceles triangle

Answer:
A quadrilateral become square if all the sides joining the co-ordinate of quadrilateral is equal
Step-by-step explanation:
Here the given co-ordinate of quadrilateral are
G (3, -1) O(1, -6)
L(-4, -4) F(-2, 1)
Line GF = 
GF = 
Similarly for line OG, OL, FL
OG = 
OG = 
OL = 
OL = 
And
FL = 
FL = 
all the sides of quadrilateral GF, OG, OL, FL all equal to 
As all the sides are equal so quadrilateral become square Answer
