Total number of members = 12
Members to choose at a time = 2
This is a combination problem and we are to find the combination of 12 objects taken 2 at a time i.e. we are to find 12C2
12C2 = 66

1400 - 650 = 750
$750 at the end of three weeks
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
