Question

In the given figure, A ABC - APQR. The value of y + z will be Q B 6 8 3 30 30% P y R А 43
(a) 2/2 +3
(b) 3/3+4
(c) 3V2+1
(d) 2/3 +2​

Answer 1

Answer:

Correct option is

B

4+33

△PQR is a right angle triangle then

(QR)2=(PR)2+(PO)2

(6)2=(y)2+(3)2

y=36−9

y=27

y=9×3

y=33

△ABC is a right angle triangle then

(BC)2=(AB)2+(AC)2

(8)2=(z)2+(43)2

z=64−48

z=16

z=4

∴y+z=4+33

Or 

This can be done using SSS criteria as both triangles are given to be similar.
