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.
-3x+5y=30
+3x+5y=30
5y=3x+30
divide 5 by everything
answer: y=3/5x+6
Answer:
1/6 of a minute.
Step-by-step explanation:
Ok so…
The answer is: 15 more marbles
Because
18 divided by 2 is 9
15+9=24
Now Chris has 9
Kevin has 24
24-9=15
Hope this helps:)
Answer:
(17 + 4)/4
Step-by-step explanation:
"of the sum of 17 and 4" = 17 + 4
"1/4 of"... = 1/4
Put the two expressions together:
1/4 * (17 + 4)
(17 + 4)/4 is your answer.
