Answer:

x = 20

Step-by-step explanation:

The converse of the same side exterior angles theorem states that <em>when two same side exterior angles are supplementary, the two lines they are on are parallel</em>.

So that means that<em> 5x + 9 and 3x + 11 are supplementary</em>.

Therefore, <em>5x + 9 + 3x + 11 = 180</em>.

Add like terms: 8x + 20 = 180

Subtract: 8x = 160

Divide: x = 20

Answer:

*To be honest, we have a bunch of ways to find x, but I'm only going to use one.

So in order for A║B, we need the outer angle of these two lines but on the opposite sides to be equal, which means:

   5x + 9 = 180 - (3x + 11)

⇔ 5x + 3x = 180 - 9 - 11

⇔ 8x         = 160

⇔ x            = 160/8 = 20

So x is equal to 20.

A boat is 400 feet away from one dock and 500 feet away from another dock the angle between the two paths is 45. What is the app
snow_lady [41]

Use the law of cosines. Let x be the distance between the docks, which forms a third leg of a triangle for which the angle opposite it has measure 45 degrees. The other two legs have lengths 400 ft and 500 ft. So

x^2=400^2+500^2-2\cdot400\cdot500\cos45^\circ

\implies x\approx356.59\,\mathrm{ft}
