Answer:

DF = 3

Step-by-step explanation:

If ABC is equivalent to EDF, then DF is equivalent to BC, which form the following ordered pairs:

D = (0,2)

F = (3,2)

It can be seen that both pairs have the same value of "y" or second value, that is 2.

As a rule, when the points are located on the y-axis (of the ordinates) or on a line parallel to this axis, the distance between the points corresponds to the absolute value of the difference of their ordinates.

So,

DF = D(x) + F(x) = 0 + 3 = 3

If we apply the equation of the distance between two points we get the same result,

DF=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}   }=\sqrt{(3-0)^{2}+(2-2)^{2}   }=\sqrt{(3)^{2}+(0)^{2}   }=\sqrt{9+0   }=\sqrt{9}=3

Hope this helps!

Answer:

  3

Step-by-step explanation:

Segment BC corresponds to segment DF. The length of BC is the distance between coordinates (0, 2) and (3, 2). These points are on the same horizontal line (y=2), so the distance between them is the difference of their x-coordinates: 3 - 0 = 3.

Answer:

x = 4

Step-by-step explanation:

Using the sine ratio on right triangle KJL

and the exact value sin30° = \frac{1}{2}

sin30° = \frac{opposite}{hypotenuse} = \frac{JL}{KL} = \frac{JL}{8\sqrt{2} } = \frac{1}{2} ( cross- multiply )

2JL = 8\sqrt{2} ( divide both sides by 2 )

JL = 4\sqrt{2}

---------------------------------------------------------

Using the sine ratio in right triangle JLM

and the exact value sin45° = \frac{1}{\sqrt{2} }

sin45° = \frac{opposite}{hypotenude} = \frac{LM}{JL} = \frac{x}{4\sqrt{2} } = \frac{1}{\sqrt{2} } ( cross- multiply )

x × \sqrt{2} = 4\sqrt{2} ( divide both sides by \sqrt{2}

x = 4

In this parallelogram m angle bad =75 so m angle bcd
Allisa [31]
The complete question in the attached figure

we know that
m angle bad =75°
remember that on parallelogram 
(∠A + ∠<span>B) = 180°
[Since, sum of the interior angles on the same side of the transversal is 180°] 
therefore
</span>∠B=180°-∠A=180°-75°=105°
∠B=105°
<span>Similarly
∠B + ∠C = 180°
∠C + ∠D = 180°
and ∠D + ∠A = 180°</span>
<span>Thus, the sum of any two adjacent angles of a parallelogram is 180°.
</span>
m angle bcd=∠C=180-∠B=180°-105°=75°

the answer is m angle bcd=75°
