2000 is blank 10 times as much what is the answer and 2000 of 1/10

Molodets [167]

2,000 is 10 times as much as 200. To find the answer we can divide 2,000 by 10:

2,000 / 10 = 200

It means that 200 is also 1/10 of 2,000.

If you want to find out what 2,000 is 1/10 of, then just multiply it by 10:

2,000 * 10 = 20,000

2,000 is 1/10 of 20,000.

<h3>Given:</h3>

Trapezium

<h3>To find:</h3>

Length of BC
Value of "x"

<h3>Solution:</h3>

We can divide the given shape into a triangle and a rectangle.

We'll have to use Pythagoras Theorem.

$\large\boxed{Formula:{a}^{2}={b}^{2}+{c}^{2}}$

In this question we have to find the hypotenuse so we'll have to add.

Let's substitute the values according to the formula.

$BC= {6}^{2}+{7}^{2}$

$BC= 85$

$BC = \sqrt{ 85}$

$\boxed{BC=9.22 \: cm}$

Now, we can find the value of "x"

Adjacent= 7 cm
Opposite= 6 cm
Hypotenuse= 9.22 cm

We can use any one from SOHCAHTOA.

Here I'm using tan.

$\large\boxed{Formula: tan(a)= \frac{opp}{adj}}$

Let's substitute the values according to the formula.

$tan \: x= \frac{6}{7}$

We'll have to use tan inverse.

$x= {tan}^{-1}(\frac{6}{7})$

$\boxed{x=40.6°}$
