Find AC for the quadrilateral
Airida [17]

The quadrilateral ABCD is an isosceles trapezoid, and the length of AC for the quadrilateral is 19 feet

<h3>How to determine the length of AC?</h3>

The quadrilateral ABCD is an isosceles trapezoid

This means that:

  • Opposite sides are equal
  • The diagonals are also equal

From the above highlights, we have:

AC = 7ft + 12ft

Evaluate the sum

AC = 19 ft

Hence, the length of AC for the quadrilateral is 19 feet

PLZ ANSWER ASAP
Vinil7 [7]
The distance formula between the line is:
\sqrt{{(x1 - x2)}^{2}  +  {(y1 - y2)}^{2} }
Thus,the distance of the above:
\sqrt{ {( - 1 - 4)}^{2}  + {(5 - 1)}^{2}  }  \\  =  \sqrt{ { - 5}^{2} +  {4}^{2}  }  \\  =  \sqrt{25 + 16 }  \\  =   \sqrt{41}  \\  = 6.4

The answer is 6.4 units.

Hope it helps!

Factor the polynomial 4b^2 - 8b
irina1246 [14]

Answer: 4b(b-2)

Step-by-step explanation: The terms 4b^2 and -8b have two things in common: they are multiples of 4 and both have at least one b. Therefore, you can pull it out of the polynomial. This would give you 4b(b-2).

Answer:

x=10

Step-by-step explanation:

Notice that all three sides of the given triangle has one tick mark.

This means that all three sides are congruent, meaning that we have an equilateral triangle.

And for equilateral triangles, all three angles are also congruent.

So:

\angle CBA=\angle BAC=\angle ACB

Also, recall that the interior angles of a triangle is always 180. Thus:

\angle CBA+\angle BAC+\angle ACB=180

Substitute:

\angle CBA+\angle CBA+\angle CBA=180

Combine like terms:

3\angle CBA=180

Substitute:

3(6x)=180

Multiply:

18x=180

Thus:

x=10

And we are done!
