Mathematics

The answer is -2

Explanation:

First of all we need to identify the problem.

Y= -X-4

We can tell already from this that the X is going to be negative.

If X=-2

Now we can change the problem to:

Y= -2-4

And can even change it to

-2-4

Well the way I learned it

A negative number minus a negative number is a negative number

A positive number minus a positive number is a positive number

Simple Right?

So what's a negative number minus a positive number?

Its a negative number!

So the answer is -6

Answer:

600.4 cm^2

Step-by-step explanation:

first we should find the base of samller triangle

hypotenuse = 35 cm

one side = 30 cm  whereas other has be be find

using pythagoras theorem

a^2 + b^2 = c^2

30^2 + b^2 = 35^2

900 + b^2 = 1225

b^2 = 1225 - 900

b^2 = 325

b = \sqrt{325}

b = 5\sqrt{13}

area of big triangle

base = 22 + 5\sqrt{13}

area of a triangle = base * height / 2

= 30 (22 + 5\sqrt{13} ) /2

=30*22 + 30*5\sqrt{13} / 2

=660 + 540.83 / 2

=1200.83 / 2

=600.415

=600.4 cm^2

Hi everybody! I need help, and this question is worth TEN points!
harkovskaia [24]

Answer:


Step-by-step explanation:

we know,

The Angle Addition Postulate states that: If a point  lies in the interior of an angle, then the postulate describes that putting two angles side by side with their vertices together creates a new angle whose measure equals the sum of the measures of the two original angles.

Here, W is the internal point.

The two angles are  UVW and WVX.

Now, by the angle addition postulate,

UVX is equal to the sum of  UVW and WVX.

Hence, the reason is-
