First one; substitute x into the equation and see if the result equal y in the coordinate
Answer:
the number of miles per hour
Step-by-step explanation:
Water can freeze at 32 degrees f
Step-by-step explanation:
angle 2 = 2x + 10 deg (corresponding angles) or 180 - 4x + 46 deg (angles on a straight line are supplementary)
therefore,
2x + 10 = 226 - 4x
6x = 216
x = 36
hence,
angle 2 = 2(36) + 10 = 82deg
