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.
Answer:
x=62
Step-by-step explanation:
The sum of x ,28, and 90 is 180 since it forms a straight line
x+28+90 = 180
Combine like terms
x+118 =180
Subtract 118 from each side
x+118-118 =180-118
x= 62
Answer:

Answer: 4
Step-by-step explanation: if 2 times y(2) is 4 what plus 4 equals 12...8 right? but you have to take 2 and multiply it by 4 in order to get 8. So the answer is 4. Hope this helps! :)
