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.
Boys : Girls : Total
33 : 11 : 44
Find the simplest form:
3 : 1 : 4
Set the total to 60 ( so we multiply by 15)
3 x 15 : 1 x 15 : 4 x 15
45 : 15 : 60
Boys = 45
Girls = 15
Total = 60
Ans: There are 15 girls that signed up
The cost of a cd after 6 year is =$ 15.12
Step-by-step explanation:
The present cost of the cd is $11.95 and inflation rate 4%
P = $11.95 , r = 4% and n = 6 years
The cost of a cd after 6 year is =
=$ 
=$ 15.12
