Answer:
Step-by-step explanation:
Here, given :
sin 2 x - 2 sin x = 2 .... (1)
Now, by <u>TRIGONOMETRIC IDENTITY</u>:
Sin 2Ф = 2 SinФ CosФ
⇒ sin 2 x = 2 sin x cos x
Putting back the value in (1), we get:
sin 2 x - 2 sin x = 2 ⇒ (2 sin x cos x) - 2 sin x = 2
or, 2( sin x cos x - sin x) = 2
or, sin x cos x - sin x = 1
or, (sin x) ( cosx - 1) = 1
⇒ Sin x = 1 / ( Cos x - 1)
Hence,
Answer:
12t = c
Step-by-step explanation:
I believe that's it
We know that
<span>The quotient of
-8x</span>²y³/xy=-8xy²
then
<span>the product of
(4xy)*z= -8xy</span>²------> z=-8xy²/(4xy)-----> z=-2y
the answer is
-2y
so
The quotient of -8x²y³/xy is same as the product of (4xy)*(-2y)
Answer:
Let affan have x no. of stamps Then,
According to the question Ayaan has 20 stamps more than 3 times the number of stamps Affan has. Then,
x = 3x + 20
Now they both have 140 stamps all together. so,
x + 3x + 20 = 140
or, 4x = 140 - 20
or x = 120/4
or, x = 30
Therefore, Affan has 30 stamps .
