□PQRS IS CYCLIC m angle SPQ =7x° and m angle SRQ= 11x° m angleSPQ
[correct question]
Given:
PQRS is a cyclic quadrilateral
To find:
The measurement of the angle SPQ
Solution:
If any of the quadrilaterals is a cyclic quadrilateral,
then, by the property of the cyclic quadrilateral, the sum of the opposite angle of the quadrilateral must be 180°.
Here we have given the angles as:
angle SPQ =7x° and angle SRQ= 11x°
and it is very clear that the given angles are opposite angles so the sum of these angles must be supplementary.
so we get,
∠SPQ + ∠SRQ = 180°
7x° + 11x° = 180°
18x = 180°
x = 10°
so,
The measurement of the angle SPQ is 7x = 7×10 = 70°
