Answer:

x = 18

Step-by-step explanation:

given that the 3 lines are parallel then the parallel lines divide the transversals proportionally , that is

\frac{3}{9} = \frac{6}{x} ( cross- multiply )

3x = 54 ( divide both sides by 3 )

x = 18

Rufina [12.5K]

Answer:

400

Step-by-step explanation:

Method for rounding:

Look at the number 1 place before the place you are rounding to.

If it is greater than 4: round up

otherwise: round down.

Ok,

here the number we're looking at is 8 cuz' 8 is in the ones place.

8 is bigger than 4 so we round up.

398.223 becomes 400

Question (in need of help)
mr Goodwill [35]
<h3><u>Required</u><u> Answer</u><u>:</u><u>-</u></h3>

This is an right angle ∆ and the side lengths containing a right angle are 9 and 11.

By Pythagoras theoram,

{p}^{2}  +  {b}^{2}  =  {h}^{2}

where p is the perpendicular, b is the base and h is the hypotenuse.

Plugging the values,

{9}^{2}  +  {11}^{2}  =  {h}^{2}

Then,

h =  \sqrt{ {9}^{2}  +  {11}^{2} }

h = 14.12(approx.)

<h3><u>Hence:</u><u>-</u></h3>

The x of the right angled ∆ = <u>1</u><u>4</u><u>.</u><u>1</u><u>2</u>
