Answer:

y = 55°

Step-by-step explanation:

You know the sum of angles in a triangle is 180°. So, ...

25° +30° +x = 180°

And, you know a linear pair of angles totals 180°:

x + y = 180°

Substituting for 180°, we have ...

25° +30° +x = x + y

Subtracting x from both sides, we get a relation that is useful to remember:

25° +30° = y

y = 55°

_____

This relation is usually described as ...

An exterior angle is equal to the sum of the remote interior angles.

Answer:men=152 women=76 children=38

Step-by-step explanation:

men+women+children=266
men=4*children
women=2*childrens
so let say x represent the numebers of children the equatin becomes: 4x+2x+x=266
solve for x =38 so the numbers of children is 38
men=4*38=152
women=2*38=76

Answer:

$8(x^2+y^2)-4x-30y+23=0$

Step-by-step explanation:

<u />

<u>Distance formula</u>

$\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Let P(x, y) = any point on the locus

Let A = (0, 2)

Let B = (-2, 3)

If a point moves such that its distance from (0, 2) is one third distance from (-2, 3):

$PA=\dfrac{1}{3}PB$

Therefore, using the distance formula:

$\implies \sqrt{(x-0)^2+(y-2)^2}=\dfrac{1}{3}\sqrt{(x-(-2))^2+(y-3)^2}$

Square both sides:

$\implies x^2+(y-2)^2=\dfrac{1}{9}[(x+2)^2+(y-3)^2]$

$\implies x^2+y^2-4y+4=\dfrac{1}{9}(x^2+4x+4+y^2-6y+9)$

Multiply both sides by 9:

$\implies 9x^2+9y^2-36y+36=x^2+4x+4+y^2-6y+9$

$\implies 8x^2+8y^2-4x-30y+23=0$

$\implies 8(x^2+y^2)-4x-30y+23=0$
