Question

13.
7. In the given figure, ZR = 90° and D is mid-point of
PR, find :
tan ZQPR
tan ZPQR
(1)
(ii)
tan ZRDQ
tan ZDQR
​

Answer 1

Answer:

ANSWER

In the given figure,

∠C=90

∘

In △ABC,

tan∠ABC=

B

P

=

BC

AC

In △CDB,

tan∠DBC=

B

P

=

BC

CD

Now,

tan∠DBC

tan∠ABC

=

BC

CD

BC

AC

tan∠DBC

tan∠ABC

=

CD

AC

tan∠DBC

tan∠ABC

=

CD

2CD

tan∠DBC

tan∠ABC

=2 (D is mid point of AC)
