since both triangles are similar
so by BPT
pq/ab = pr/bc= qr/ac
so first we can take
pq/ab=pr/bc
3/z = 6/ 8
z= 4cm
pq/ab = qr/ac
3/4 = y/4✓3
y=3✓3
z+y = 4cm + 3✓3cm
so by BPT
pq/ab = pr/bc= qr/ac
so first we can take
pq/ab=pr/bc
3/z = 6/ 8
z= 4cm
pq/ab = qr/ac
3/4 = y/4✓3
y=3✓3
z+y = 4cm + 3✓3cm

Given:
- ΔPQR ≅ ΔABC
To Find:
- The values of x and y.
Solution:
- From the figure, we get to know that ΔPQR is a right-angled triangle.
- Using the Pythagoras theorem,
- ⇒
- Substituting the values,
- ⇒ 36 = + 9
- ⇒ y = = =
- y = cm
- Consider the second ΔABC which is a right-angle triangle,
- Again using the Pythagoras,
- ⇒
- Substituting the values,
- ⇒
- ⇒
- z = = = 4
- z = 4 cm
The Values of y and z are cm and 4 cm respectively.
