SOLUTION
TO CHOOSE THE CORRECT OPTION
In a ΔPQR, ∠Q=90°, if PQ = 10 cm and PR = 15 cm, then the value of tan²P + sec²P + 1 is.
(a) 5/2
(b)3/17
(c)9/2
(d)4/5
EVALUATION
Here it is given that in a ΔPQR, ∠Q=90°, if PQ = 10 cm and PR = 15 cm
Then sec P
Now we have
tan²P + sec²P + 1
= 1 + tan²P + sec²P
= sec²P + sec²P
= 2 sec²P
FINAL ANSWER
Hence the correct option is
