Q.3: Solve the following equation and find the value of .
(A) 60o
(B) 30o
(C) 15o
(D) 45o
Show Answer
Put
3 x cot60 + tan60 -2
so
Q.4: In ,
, AB = 20cm and BC = 29cm. What is the value of (sinB -cotC) ?
(A)
(B)
(C)
(D)
Show Answer

Q.5: If tanx = cot(48o + 2x), and 0o <x <90o , then what is the value of x ?
(A) 14o
(B 12o
(C) 21o
(D) 16o
Show Answer
tan x = cot (48 + 2x)
tanx = tan (90 – (48 + 2x)
x = 90 -(48 + 2x)
x = 90 – 48 – 2x
3x = 42
x = 14
