Does the point (-4, 2) lie inside or outside or on the circle x^2 + y^2 = 25?

stiv31 [10]

Given equation of the Circle is ,

$\sf\implies x^2 + y^2 = 25$

And we need to tell that whether the point (-4,2) lies inside or outside the circle. On converting the equation into Standard form and determinimg the centre of the circle as ,

$\sf\implies (x-0)^2 +( y-0)^2 = 5 ^2$

Here we can say that ,

• Radius = 5 units

• Centre = (0,0)

Finding distance between the two points :-

$\sf\implies Distance = \sqrt{ (0+4)^2+(2-0)^2} \\\\\sf\implies Distance = \sqrt{ 16 + 4 } \\\\\sf\implies Distance =\sqrt{20}\\\\\sf\implies\red{ Distance = 4.47 }$

Here we can see that the distance of point from centre is less than the radius.

Hence the point lies within the circle .

Two angles are congruent and supplementar

Romashka [77]

You are told that the two angles are supplementary. That means that when you add the measure
of angle A (call it mA) and the measure of angle B (call it mB) the resulting sum is 180 degrees.
This relationship can be written in equation form as:
.
mA + mB = 180
.
You are also told that the two angles are congruent. This means that their measures
are equal. You can write this relationship as the equation:
.
mA = mB
.
From this second equation you can see that wherever you have mA you can substitute mB
in its place because they are equals. So go back to the equation:
.
mA + mB = 180
.

In place of mA substitute mB. This makes the equation become:
.
mB + mB = 180
.
On the left side you can see that the sum is 2 times mB or 2*mB. Make this simplification
to get:
.
2*mB = 180
.
To solve for mB divide both sides of this equation by 2. When you do that division the
equation reduces to:
.
mB = 180/2 = 90
.
This tells you that the measure of angle B is 90 degrees, and that means that the measure
of angle A is also equal to 90 degrees because the two angles are congruent.

I hope this helps!

Fill in the blank with the correct response. Given ∠1=∠2, find x.

dexar [7]

Answer:

x = 6

Step-by-step explanation:

Since, ∠1 ≅ ∠2

By angle bisector theorem,

$\frac{AB}{BD}=\frac{AC}{CD}$

By substituting the measures of each side in the given ratio of the sides,

$\frac{3}{x-4}=\frac{x}{4}$

12 = x(x - 4)

12 = x² - 4x

x² - 4x - 12 = 0

x² - 6x + 2x - 12 = 0

x( x - 6) + 2(x - 6) = 0

(x + 2)(x - 6) = 0

x = -2, 6

Since, measure of the sides can't be negative, x can not be negative.

Therefore, x = 6 will be the answer.
