Given:
Point Q is on line segment PR.
QR = 3x, PQ = x + 6, and PR = 5x – 4.
To find:
The numerical length of PQ.
Solution:
Since, point Q is on line segment PR, so by segment addition property, we get
The value of x is 10.
Now,
Putting x=10, we get
Therefore, the numerical length of PQ is 16 units.
Drawing out the triangle, we get the one below. We can use the trigonometric ratio of tan to solve this problem.
x=21.5
