Answer:
-1
Step-by-step explanation:
I thought to pass it off! But I understand your situation and urgency.
First, let us find the value of 'y' by using pythagoras theorem which says that,
(side) ² + (side)² = (hypotenuse)²
=> (10)² + (y)² = (20)²
=>y² = 400-100
=> y = √(300)
=> y = 10√3
So,
now, we know that,
tan A = Opp. to A/ Adj. side of A (generally)
=> tan x (here) = AB/BC
=> tan x = 10√3/10
=> tan x = √3
S0,tan²x = (√3)² = 3
Sin A = Opp. side of A/Hypotenuse (generally)
=>Sin x (here in question) = AB/BC
=> Sin x = 10√3/20
=> Sin x = √3/2
So, now,
Sin² x = 3/4
Now,
(1/tan² x) - (1/sin² x)
= (1/3) - (4/3)
= -3/3
= -1
Hope it helps.
