If point A ( -3, -2) is reflected across the y-axis what is the coordinate of the image of A?

Hey!!! PLS Help <br> If ∠6 = 68°, find the measures of angles 4, 5, 7.

irina [24]

Answer:

Find the measure of the indicated angle. (remember that the sum of interior angles is equal to 180 degrees) Q. Find the measure of each angle indicated. Q. If all three angles are exactly the same measure, how big is each angle? Q. Find the missing angle. Q. Find the measure of the angle x. Q.

Step-by-step explanation:

If angle 1 is 135 degrees, how many degrees is angle 3? Q. What angle pair is pictured? Q. Find the measure of the indicated angle. (remember that the sum of interior angles is equal to 180 degrees) Q. Find the measure of each angle indicated. Q. If all three angles are exactly the same measure, how big is each angle? Q. Find the missing angle.

FaSSSSSSTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTT and thanks yall are fast

Mama L [17]

Answer:

120 degrees

Step-by-step explanation:

It's a vertical angle, meaning that it is congruent to the one on the opposite side of it.

the rectangle shown has an area of 105 square inches. the width is x+ 16 inches and the length is x. find the dimensions of the

Brums [2.3K]

Answer:

Length = 5

Width = 21

Step-by-step explanation:

(x)(x + 16) = 105

x^2 + 16x = 105

x^2 + 16x - 105 = 0

(x - 5) x ( x + 21) = 0

x - 10 = 0

x = 5

x + 21 = 0

x = -21

Now that we have the zeroes.

We have to find the most viable one to put in.

Using -21 would not make sense, so we will use 5.

Plug it in:

x = 5

(5) (5 + 16) = 105

5 ( 21) = 105

HOW DO I FIND QR<br><br> PLEASE HELP

Paul [167]

Solution: For finding QR we need to apply Pythagoras Theorem

What is Pythagoras Theorem ?

ans : Pythagoras Theorem is the sum of square of two sides which is equal to the third side or the hypotenuse. This formula is valid oy incase of Right-Angled Traingle because one of three angles here is 90°

According to this law let's apply it in the diagram shown here.

(Hypotenuse)² = (Adjacent)² + (Opposite)²

(PR)² = (QR)² + (PQ)²

(5x - 2)² = (QR)² + (3x - 1)²

(QR)² = (5x - 2)² - (3x - 1)²

After factorising both of them we get

(QR)² = 25x² - 20x + 4 - (9x² - 6x + 1)

(QR)² = 25x² - 20x + 4 - 9x² + 6x - 1

(QR)² = 16x² - 14x + 3

QR = √(16x² - 14x + 3)

So, QR is √(16x² - 14x + 3)

Identify the equivalent expression for each of the expressions below. Root(5, (m + 2) ^ 3). Root(3, (m + 2) ^ 5). Root(5, m ^ 3)

vesna_86 [32]

Answer:

1. $(\sqrt[5]{(m+2)})^{3} = (m+2)^{\frac{3}{5}}$

2. $(\sqrt[3]{(m+2)})^{5} = (m+2)^{\frac{5}{3}}$

3. $\sqrt[5]{(m)}^{3}+2 = m^{\frac{3}{5}}+2$

4. $\sqrt[3]{(m)}^{5}+2 = m^{\frac{5}{3}}+2$

Step-by-step explanation:

Recall that

$(\sqrt[n]{x})^{m} = (x^{\frac{m}{n}})$

Where $x^{m}$ is called radicand and n is called index

1. Root(5, (m + 2) ^ 3)

In this case,

n is 5

m is 3

x = (m + 2)

$(\sqrt[5]{(m+2)})^{3} = (m+2)^{\frac{3}{5}}$

2. Root(3, (m + 2) ^ 5)

In this case,

n is 3

m is 5

x = (m + 2)

$(\sqrt[3]{(m+2)})^{5} = (m+2)^{\frac{5}{3}}$

3. Root(5, m ^ 3) + 2

In this case,

n is 5

m is 3

x = m

$\sqrt[5]{(m)}^{3}+2 = m^{\frac{3}{5}}+2$

4. Root(3, m ^ 5) + 2

In this case,

n is 3

m is 5

x = m

$\sqrt[3]{(m)}^{5}+2 = m^{\frac{5}{3}}+2$
