Answer:

x = 20°

Step-by-step explanation:

The angle measures should add up to 180 degrees. So that leaves us with 100 degrees left to find if we take out the 80 given.

3x + 2x simplifies to 5x. 5x must equal 100.

100/5 = 20.

Therefore x = 20.

A passenger rode the subway 2 blocks west and then 10 south. If all the blocks are the same length what is the value of the slop

Nimfa-mama [501]

Answer:

The slope of the line is 5

Step-by-step explanation:

Great question, it is always good to ask away and get rid of any doubts that you may be having.

I have created an illustration which is attached below in order to help you understand the situation. As we are told the passenger rode the subway from point (0 , 0) to point (-2, 0). Then he rode the subway from point (-2, 0) to the final destination of point (-2 , -10). In order to find the value of the slope we need to use the slope formula which is

$Slope = \frac{y_{2}-y_{1} }{x_{2}- x_{1} }$
