Answer:
sin θ . tan θ
Step-by-step explanation:
Note : -
sec ( - θ ) = sec θ
Formula / Identity : -
sec θ = 1 / cos θ
sec ( - θ ) - cos θ
= [ 1 / cos θ ] - cos θ
{ LCM = cos θ }
= [ 1 / cos θ ] - [ cos²θ / cos θ ]
= [ 1 - cos²θ ] / cos θ
{ 1 - cos²θ = sin²θ }
= sin²θ / cos θ
{ sin²θ = sin θ . sin θ }
= sin θ . sin θ / cos θ
{ sin θ / cos θ = tan θ }
= sin θ . tan θ
Hence, simplified.
Answer:
5 3/4 IBS
Step-by-step explanation:
The degree of the radian angle 0.11 is 
Explanation:
It is given that the radian angle is 0.11
We need to determine the degrees of the radian angle.
To convert the radian into degrees, let us multiply the radian with 
Thus, we have,
It is given that 
Substituting in the above expression, we have,
Rounding off to the nearest tenth, we have,
Thus, the degree of the radian angle 0.11 is
The full price is $82, (100%), the discounted price is $65.60, (?%)
So lets see something:
$82 ------------- 100%
$65.60 --------------- x%
Multiply in cross
82.x = 65,60 . 100
82x = 6560
Divide both sides by 82
82x/82 = 6560/82
x = 80
So the discounted price is equal to 80% of the initial price
100% - 80% = 20% so the discount is 20%
