You can estimate 7 2/5 to 7 and estimate 6 3/8 to 6 1/2. And add them both up. If u add them, you get 13 1/2

Which statements is an example of the symmetric property of congruence?

jok3333 [9.3K]

Answer:

I believe the answer is C.

Step-by-step explanation:

Example:

For any angles A and B , if ∠ A ≅ ∠ B , then ∠ B ≅ ∠ A . Order of congruence does not matter.

Find the distance of the point (3,4) from the midpoint of the line joining (8,10) and (4,6)

Elis [28]

Answer:

Distance between point $(3,4)$ and midpoint of line joining $(8,10)$ and $(4,6)$ = $5$ units.

Step-by-step explanation:

Given:

Points:

$A(3,4)\\B(8,10)\\C(4,6)$

To find distance from point A to midpoint of BC.

Midpoint M of BC:

$M=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})\\$

$M=(\frac{8+4}{2},\frac{10+6}{2})\\$ [Plugging in points $B(8,10)\ and\ C(4,6)$ ]

$M=(\frac{12}{2},\frac{16}{2})\\$

$M=(6,8)\\$

Distance between A and M:

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

$D=\sqrt{(6-3)^2+(8-4)^2} \\$ [Plugging in points $A(3,4)\ and\ M(6,8)$ ]

$D=\sqrt{(3)^2+(4)^2} \\$

$D=\sqrt{9+16} \\$

$D=\sqrt{25} \\$

$D=\pm5$

Since distance is always positive ∴ $D= 5$ units

Triangle ABC is congruent to triangle DEF. If DE = 41, EF = 23, DF = 36, and AC = 5x - 9, what is x? Round to the nearest tenth.

Aloiza [94]

Similar shapes may or may not be congruent.

The value of x is (a) 9.0

The corresponding sides are:

AB and DE
BC and EF
AC and DF

The side lengths are:

$\mathbf{DE = 41}$

$\mathbf{EF = 23}$

$\mathbf{DF = 36}$

$\mathbf{AC = 5x - 9}$

Because the shapes are congruent, and AC corresponds to DF.

This means that:

$\mathbf{AC = DF}$

So, we have:

$\mathbf{5x - 9 = 36}$

Collect like terms

$\mathbf{5x = 9 + 36}$

$\mathbf{5x = 45}$

Divide both sides by 5

$\mathbf{x = 9.0}$

<em>Hence, the correct option is (a) 9.0</em>

14 is whatpercent of 25

hjlf

Answer: the answer is 56

Hope this Help

Step-by-step explanation:

100%= 25

X%= 14

100%=25(1)

X% = 14(2)

100%/x% = 25/14

X%/ 100% = 14/25

X=56%
