Cos(x+y)/cosxcosy+tanxtany=1

adelina 88 [10]

Answer:

See explanation

Step-by-step explanation:

Use formula

$\cos (x+y)=\cos x\cos y-\sin x\sin y$

Substitute it into the first fraction:

$\dfrac{\cos (x+y)}{\cos x\cos y}\\ \\=\dfrac{\cos x\cos y-\sin x\sin y}{\cos x\cos y}\\ \\=\dfrac{\cos x\cos y}{\cos x\cos y}-\dfrac{\sin x\sin y}{\cos x\cos y}\\ \\=1-\dfrac{\sin x}{\cos x}\cdot \dfrac{\sin y}{\cos y}\\ \\=1-\tan x\tany$

Consider the whole expression:

$\dfrac{\cos (x+y)}{\cos x\cos y}+\tan x\tan y\\ \\=1-\tan x \tan y+\tan x\tan y\\ \\=1$

Done!

Evaluate the expression when the value of the variable is given. 40 - 8x when x = 2

Ede4ka [16]

Answer:

Step-by-step explanation:

To evaluate this, we just need to substitute 2 for whenever we see x.

40 - 8 (2)

From here, we can just use order of operations to simplify it down to a single number.

40 - 16

So, when x = 2, we get 24.
