(8-4x+2y)-(20+4x-4y)
-12-8x+6y or -8x+6y-12
1303/12.8 is the answer for that one which it should land in the middle of the line!
Answer: The angles are 30 30, 150, 150
Step-by-step explanation: Two lines intersect means they cross. According to the vertical angle theorem, angles that are across are the same, a line is 180 degrees so it means the angles that make up the supplementary pair add up to 180(180-30=150). So there are 2 150 degree angles and 2 30 degree angles
Answer:
3 11/12 in.
Step-by-step explanation:
The radius is simply half of the diameter.
7 5/6 divide by 2 = 3 11/12
