<h2>Answer:</h2>

The value of x is:

                              x=25

<h2>Step-by-step explanation:</h2>

As we know that if a transversal divides the two parallel lines then the corresponding exterior angles have the same measure.

Here after looking at the two angles which are marked we observe that they make a pair of corresponding exterior angles.

i.e. both are equal.

i.e.

x+40=3x-10\\\\i.e.\\\\3x-x=40+10\\\\i.e.\\\\2x=50\\\\i.e.\\\\x=\dfrac{50}{2}\\\\i.e.\\\\x=25

A rectangle on a coordinate plane is translated 5 units up and 3 units to the left. Which rule describes the translation?
DedPeter [7]

Answer:

C

Step-by-step explanation:

Any time you move up or down, it affects the "y" coordinate, and going up is positive so 5 units up is y + 5.

Moving left or right affects the "x" coordinate and moving left is negative so

x - 3

(x - 3, y + 5)

 Hence, C is the correct answer

Solve the equation for θ, where
elena-s [515]

Answer:

\dfrac{\pi}{4},\dfrac{3\pi}{4}

Step-by-step explanation:

2\sin^2(\theta)=1

Divide both sides by 2:

\sin^2(\theta)=\dfrac{1}{2}

Take the square root of both sides:

\sin(\theta)=\dfrac{1}{\sqrt{2}}=\dfrac{\sqrt{2}}{2}

The only two places on the unit circle where the y value of the point is \dfrac{\sqrt{2}}{2} are at:

\dfrac{\pi}{4},\dfrac{3\pi}{4}

Hope this helps!

Alicia can row 6 miles downstream in the same time it takes her to row 4 miles upstream.She rows downstream miles/hour faster th
disa [49]

Answer:

Option D. 9 mi/hr downstream, 6 mi/hr upstream

Step-by-step explanation:

<u><em>The complete question is</em></u>

Alicia can row 6 miles downstream in the same time it takes her to row 4 miles upstream. She rows downstream 3 miles/hour faster than she rows upstream. Find Alicia’s rowing rate each way

Define the variables

Let

x -----> Alicia's rowing rate downstream in miles per hour

y ----> Alicia's rowing rate upstream in miles per hour

we know that

The rate is equal to the distance divided by the time

so

The time is equal to the distance divided by the rate

we have

\frac{6}{x}=\frac{4}{y}

4x=6y

x=1.5y -----> equation A

x=y+3 ----> equation B

equate equation A and equation B

1.5y=y+3

1.5y-y=3

0.5y=3

y=6

<em>Find the value of x</em>

x=1.5(6)=9

therefore

Alicia's rowing rate downstream is 9 mi/h

Alicia's rowing rate upstream is 6 mi/h
