Answer:
x = pi/2..only
Step-by-step explanation:
The equation states that...,
tan^2x.sin x = tan^2x
;we simplify the equation by dividing both sides by tan^2x...which then leaves our equation as,
; sin x = 1
; x = sin^-1 (1)
; Hence x = pi/2
2.74x=58.19
x=21.2372

Answer:
is the same as 
by co-function identities
Step-by-step explanation:
Remember that complementary angles add up to 90°. The angle that i s complementary to 63° is 27°.
Also recall the co-function identities:
- sin (90° – x) = cos x
- cos (90° – x) = sin x
This means that 
.
