Answer: The system consists of parallel lines
Step-by-step explanation:
Given system of lines :
Substitute in
, we get
, which is not true.
That means , system has no solution.
i.e. they are representing parallel lines. [Parallel lines do not intersect and hence they do not have solution.]
Given:
A quadrilateral inscribed in a circle.
To find:
The values of a and b.
Solution:
A quadrilateral inscribed in a circle. So, the quadrilateral is a cyclic quadrilateral.
We know that the sum of the opposite angles of a cyclic quadrilateral is 180 degrees.
We know that the measure of arc is twice of measure of subtended angle on that arc.
Therefore, the value of a is 101 degrees and the value of b is 82 degrees.
