I don't know what you mean by "Broken apart," but I'll do my best...

20 x 90 = 1800

9 x 7 = 63

1800 + 63 = 1863

I hope this helped you! :)

Ipatiy [6.2K]

Train A speed= 70 km/h north
Train B speed= 75 km/h south
Opposite directions= add speeds 70+75=145
Distance= 435 Km
Time= d/s; 435/145= 3 hours
It would take 3 hours for the trains to be 435 kilometers apart

Prove that 1-tan^2x/1+tan^2x=2cos^2x-1

katen-ka-za [31]

Answer:

see explanation

Step-by-step explanation:

Using the trigonometric identities

tan x = $\frac{sinx}{cosx}$ , sin²x + cos²x = 1

Consider the left side

$\frac{1-tan^2x}{1+tan^2x}$

= $\frac{1-\frac{sin^2x}{cos^2x} }{1+\frac{sin^2x}{cos^2x} }$ ← multiply numerator/ denominator of the whole fraction by cos²x

= $\frac{cos^2x-sin^2x}{cos^2x+sin^2x}$

= $\frac{cos^2x-sin^2x}{1}$

= cos²x - sin²x

= cos²x - (1 - cos²x)

= cos²x - 1 + cos²x

= 2cos²x - 1

= right side , thus proven
