Answer:

2/11

Step-by-step explanation:

You would have to do 2 times 10 which equals 20. Than 5 times 22 which is 110. No to reduce you have to find the Greatest Common faction which is 10. So 20 divided by 10 equals 2 and 110 divided by 10 is 11.

Please help me if u do ill give to the best brainliest :)

Step-by-step explanation:

t in 1200m:

$t = \frac{4500}{x} \\ x = 1200 \\ t = 4500 \div 1200 = 3.75$

t in 3750:

$t = \frac{4500}{x} \\ x = 3750 \\ t = 4000 \div 3750 = 0.12$

difference is:

3.75-0.12 = 3.63

Tan x + tan 2x = 0

choli [55]

stated method in question is wrong!

Step-by-step explanation:

We need to find the general solution of x ! for the equation $tan x + tan 2x = 0$

⇒ $tan x + tan 2x = 0$

⇒ $(tan x + tan 2x)-tan2x = 0-tan2x$

⇒ $tan x = -tan2x$

Now , we know that $tan(\pi -2x) = -tan2x$

⇒ $tan x = -tan2x$

⇒ $tan x = tan(\pi -2x)$

Now , we know that $TanA = TanB \\A=B$

⇒ $tan x = tan(\pi -2x)$

⇒ $x = \pi -2x$

⇒ $3x = \pi$

⇒ $x = \frac{\pi}{3}$ ......(1)

General solution of Tan x is : $x = n\pi + \alpha$ , \

Here , from equation (1) we get $\alpha =\frac{\pi }{3}$ . Hence general solution is :

⇒ $x = n\pi +\frac{\pi }{3}$ .Therefore , stated method in question is wrong!

Answer:

164 m^2

Step-by-step explanation:

You can think of the shaded area in different ways. One of the ways is the entire outer colored rectangle minus the area of the small white rectangle inside.

The large colored rectangle is 12 m by 15 m.

The inner rectangle is 8 m tall. The width is 12 m - 5 m - 5 m = 2 m

A = 12 m * 15 m - 2 m * 8 m

A = 180 m^2 - 16 m^2

A = 164 m^2
