(PQ)^2=(PS)^2+(SQ)^2
(PQ)^2=(3)^2+(4)^2
(PQ)^2=9+16
(PQ)^2=25
(PQ) =5

Answer:
The value of tanθ is .
Step-by-step explanation:
From the figure it is clear that
It means triangle PSQ is a right angled triangle.
Using Pythagoras theorem in triangle PQS, we get
The length of PQ is 5 cm.
It means triangle PQR is a right angled triangle. In a right angle triangle
Therefore the value of tanθ is .
