Question

If tanA=3/4 then find the value of (3+2cosecA)(1-3secA)/5+secA)(2-3cosecA)

Answer 1

Answer:

326.390625

Step-by-step explanation:

tan A=3/4

cot A= 4/3

sin A=3/5

cosec A= 5/3

cos A=4/5

sec A= 5/4

(3+2cosecA)=(3+2×5/3)

(3+10/3)

6.33

(1-3secA)=(1-15/4)

= -2.75

(5+secA)=(5+5/4)

=6.25

(2-3cosecA)=(2-15/3)

= -3

(3+2cosecA)(1-3secA)/5+secA)(2-3cosecA)

(3+2×5/3)(1-3×5/4)(5+5/4)(2-3×5/3)

(3+10/3)(1-15/4)(5+5/4)(2-15/3)

(6.33)(-2.75)(6.25)(-3)

=326.390625
