When multiply or divide an inequality by a negative number, flip the direction of the sign (ex, from < to > or vice verca)
28>4-2p
minus 4 from both sides
24>-2p
divide both sides by -2 and don't forget to flip the sign
-12<p
p>-12
Answer:
/_FCB
Step-by-step explanation:
As, supplementry means they add up to 180°
So a straight angle = /_DCB = 180°
So /_DCF + /_x = /_DCB
So, /_x = /_FCB
So answer = /_FCB
We have this equation:
So, we need to solve this equation for L. Then we sum -2W in each member of the equation, like this:
Then, dividing the equation by 2:
Finally, let's order this equation:
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.
