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)

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.
Total angle for the pie chart = 360°
13 out of 60 = 13 / 60
Angle for it = 13 / 60 * 360 = 13 * 6 = 78°
Angle used = 78°

Answer:
(8, 72)
Step-by-step explanation:
Here we have two separate equations for y: y = 9x and y = 2x + 56.
Equating these equations eliminates y temporarily; we get:
9x = 2x + 56, or 7x = 56. Dividing both sides by 7 results in x = 8.
Then, by the first equation, y = 9(8) = 72.
The solution is (8, 72).
