Jones Street is parallel to Lincoln Street, and both streets are intersected by Elm Street and Avenue A. Jones Street J 105° m E

kvv77 [185]

We have:

Alternate angles are equal in measure, therefore:

$\angle E=105^{\circ}$

Then, The angles E, JEA and 32° add up to 180° because they form a straight angle. So:

$\begin{gathered} 105+\angle JEA+32=180 \\ 137+\angle JEA=180 \\ 137+\angle JEA-137=180-137 \\ \angle JEA=43 \end{gathered}$

Answer: 43°

The function f(x) is defined as (1/2)x - 7. Emma says one possible value for the function is (2, -6). Is she correct?

Deffense [45]

Yes, she is correct. If you plug 2 into the equation, you will see this:

(1/2)(2) -7
1-7
= -6

So, the pair of values is (2,-6). Emma is correct.

You want to paddle a canoe across a small lake and want to know how far it is to the other side. You take measurements ln your s

krek1111 [17]

Answer:

$x= 5*400 ft = 2000 ft$

Step-by-step explanation:

For this case we can use the figure attached and we are interested in order to find the value of x.

We have two similar triangles (DEC and ABC) and we can find the scale factor like this:

$Factor= \frac{EC}{BC}=\frac{500ft}{100ft}=5$

And now we can apply proportions in order to find the value of x using the two sides DE and BA, since we have the ratio between the triangle DEC and ABC we have this:

$Factor=5=\frac{x ft}{400 ft}$

And solving for x we got:

$x= 5*400 ft = 2000 ft$

And then the distance across the lake would be 2000 ft
