Answer:
Step-by-step explanation:
(2 , 1) ; ( 3 , 2)
Equation of line: y = mx +b
y = 1x + b
Plugin x = 2 and y = 1 in the above equation
1 = 2 + b
1- 2 = b
b = -1
y = 1x - 1

Given:
PQRS is a circle, PQT and SRT are straight lines.
To find:
The value of x.
Solution:
Since PQRS is a circle, PQT and SRT are straight lines, therefore, PQRS isa cyclic quadrilateral.
We know that, sum of opposite angles of a cyclic quadrilateral is 180 degrees.
Now, SRT is a straight line.
(Linear pair)
...(i)
According to the Exterior angle theorem, in a triangle the measure of an exterior angle is equal the sum of the opposite interior angles.
Using exterior angle theorem in triangle QRT, we get
Therefore, the value of x is 103 degrees.
