Answer:

Red and Green are parallel

Black and Blue are perpendicular

Step-by-step explanation:

Parallel lines need to have the same slope. Lines red and green both have a slope of 1/2.

The slopes of two lines that are perpendicular have to be opposite reciprocals, and must be multiplied together to get -1. Line black has a slope of -4, and line blue has a slope of 1/4. Both of them multiplied together equals -1.

I need geometry help

fiasKO [112]

I believe you can do x + 2.7 = 16.

I took geometry last year and those arrow things are basically saying the line is the same if they have the same number of arrows. Using that logic, you can equal them out and find X.

Your answer is 16 - 2.7
(13.3)
