Answer:

x = 40

Step-by-step explanation:

Here's a fun fact, all of those angles actually add up to 360 degrees!

How do we know this? Well if you were to draw a small arc between each of the lines, you would see that the arc would end up making a circle. And remember, circles have 360 degrees!

Now we can do some basic algebra. Add up all the angles and set that equal to 360.

(2x) + (x) + (3x + 20) + (2x+20) = 360.

8x + 40 = 360

8x = 320

x = 40

Hope this helped!

Write an equation in​ slope-intercept form of the line that passes through the given point and is perpendicular to the graph of
Keith_Richards [23]

Answer:

y = -5x - 17

Step-by-step explanation:

Linear equations, or lines, that are perpendicular to each other have opposite reciprocals for the value of slope.  For the given line, y = 1/5x - 2, the slope is 1/5 and the opposite reciprocal is -5.

Given the value of the slope and a given point on the second line, you can solve for 'b':

y = mx + b

8 = (-5)(-5) + b

8 = 25 + b

-17 = b

y = -5x - 17

alex41 [277]

Answer:

the length of the bridge in miles is 3.37 miles

Step-by-step explanation:

The computation of the length of the bridge in miles is shown below:

Given that

The length is 5927.261 yard

As we know that

1760 yard = 1 mile

So 1 yard = 1 ÷ 1760 mile

For 5927.261 yard, the miles would be

= 5927.261 ÷ 1760

= 3.37 miles

Hence, the length of the bridge in miles is 3.37 miles
