Answer:

if ∠PQR ≅ ∠STU, then ∠STU ≅ ∠PQR

We conclude that 'Symmetric Property of Angle Congruence' illustrates this statement.

Step-by-step explanation:

We know that the Symmetric Property of Angle Congruence can be defined as

For any angles X and Y, if ∠X≅∠Y , then ∠Y≅∠X

For example, Let suppose

m∠X = 20

m∠Y = 20

As ∠X≅∠Y i.e. 20 ≅ 20

then

∠Y≅∠X i.e. 20 ≅ 20

Given

if ∠PQR ≅ ∠STU, then ∠STU ≅ ∠PQR

Thus, we conclude from the above discussion that 'Symmetric Property of Angle Congruence' illustrates this statement.

I need to know the answer I’m working on rational numubers

lesya [120]

Answer:

Fraction Form: $\frac{11}{24}$

Decimal Form: 0.4583

Step-by-step explanation:

Apply the fraction rule: $\frac{-a}{b} = - \frac{a}{b}$

$\frac{-5}{12} = - \frac{5}{12}$

$- \frac{5}{12} + \frac{7}{8}$

Least Common Multiple (LCM) of 12 and 8: 24

$- \frac{5}{12} x \frac{2}{2} = - \frac{10}{24} \\\\\frac{7}{8} x \frac{3}{3} = \frac{21}{24} \\\\- \frac{10}{24} + \frac{21}{24}$

Apply the fraction rule:

$\frac{a}{c} + \frac{b}{c}= \frac{a + b}{c}\\\\\frac{-10 + 21}{24} \\\\-10 + 21 = 11\\\\\frac{11}{24}$

Krystal’s poster project for reading class is 2 feet high and 1 1 2 feet wide. Her friend Victoria’s poster is 4 feet high and 1

Bess [88]

The area of Victoria's poster is twice the area of Krystal's poster.

<h3>How compare the areas of two similar posters</h3>

The two areas are shown in the image attached below. Each poster represents a rectangle and the ratio between the two areas ( $r_{A}$ ), no unit, is defined by the following formula:

$r_{A} = \frac{w_{V}\cdot h_{V}}{w_{K}\cdot h_{K}}$ (1)

Where:

$w_{V}$ - Width of Victoria's poster, in feet.
$h_{V}$ - Height of Victoria's poster, in feet.
$w_{K}$ - Width of Krystal's poster, in feet.
$h_{K}$ - Height of Krystal's poster, in feet.

If we know that $h_{V} = 4\,ft$ , $w_{V} = 1.5\,ft$ , $h_{K} = 2\,ft$ and $w_{K} = 1.5\,ft$ , then the ratio between the two areas is:

$r_{A} = \frac{(4)\cdot (1.5)}{(2)\cdot (1.5)}$

$r_{A} = 2$

The area of Victoria's poster is twice the area of Krystal's poster. $\blacksquare$

Please help im so confused!!??

victus00 [196]

The formula for the surface area of a cone is SA=(pi)(r^2)+(pi)(r)(l)

L is the slant height of the cone.
Because pi is in the answer choices, there is no need to multiply either by pi so the new formula becomes
SA=r^2+(r)(l)
Now you just plug in what you know
Sa=(8^2) + (8)(15)
Sa=64+120
Sa=184(pi)

*dont forget to put the pi back in since you took it out in the beginning of the equation*

Your answer is A.

Hope this helps :)
