If the hypotenuse of a right triangle is 8 and one leg is 6, what is the length of the other leg?
qwelly [4]

Answer:

5.3

Step-by-step explanation:

pythagorean theory :,)

a^{2} + b^{2} = c^{2}

the legs are a and b, while the hypotenuse (the longest side) is c

fill in the equation with the information u have and simplify so

a^{2} + 6^{2} = 8^{2}

a^{2} + 36 = 64

now get the variable (a) by itself

a^{2} + 36 = 64\\

(subtract 36 on both sides)

a^{2} = 28

a = 5.3

square root of both sides ≈ 5.3

(you could also multiply the square root of 7 by 2)

Given m\parallel nm∥n, find the value of x and y.
Sindrei [870]

Answer:

See below ↓↓

Step-by-step explanation:

<u>Finding x</u>

  • Both the angles containing the x variable are on the same side of the transversal
  • There is a property which states that : two angles on the same side of the transversal are supplementary
  • Therefore, they add up to 180°
  • ⇒ 8x + 12 + 2x + 18 = 180
  • ⇒ 10x + 30 = 180
  • ⇒ 10x = 150
  • ⇒ <u>x = 15</u>

<u></u>

<u>Finding y</u>

  • The angles at the top are vertically opposite angles (VOA), meaning that they are equal
  • ⇒ 8x + 12 = 3y - 18
  • ⇒ 3y = 8(15) + 12 + 18
  • ⇒ 3y = 120 + 30
  • ⇒ 3y = 150
  • <u>⇒ y = 50</u>

VikaD [51]

12x^2+9x^3-6x^4\\\\LCD(12,\ 9,\ 6)=3\\\\LCD(x^2,\ x^3,\ x^4)=x^2\\\\12x^2=(3x^2)(4)\\9x^3=(3x^2)(3x)\\-6x^4=(3x^2)(-2x^2)\\\\GCF\ of\ 12x^2+9x^3-6x^4\ is\ equal\ \boxed{3x^2}\\\\12x^2+9x^3-6x^4=(3x^2)(4+3x-2x^2)
