liraira [26]

Answer:

$120

Step-by-step explanation:

40% of the earnings is spent on rent.

The earnings is an unknown, so we call it x.

The rent is $800, so 40% of x equals $800.

40% * x = 800

0.4x = 800

x = 800/0.4

x = 2000

She earns $2000 per month.

After paying rent, the remaining amount is

$2000 - $800 = $1200

She spends 10% of the remaining amount on entertainment.

10% of $1200 = 10% * $1200 = 0.1 * $1200 = $120

Help me please. How to prove this ?

podryga [215]

Answer:

First, you want to divide the numerator and denominator by the cosine(x), and afterwards, it looks like this...

$\frac{tan~x+1}{tan~x-1}$

Include 45 as one of the parameters and correlate with tan.

$\frac{tan~x+tan~45}{tan~x-tan~45}$

Next, you want to multiply the numerator and denominator by the conjugate of the denominator, in this case, tan x + tan 45.

Lastly, simplify, and you have the answer as tan(45 + x)
