I'm gonna say C for this one
The product of $0.89 x 14 equals 12.46
By using distance formula (which is attached below), you can solve this problem:
√(x2-x1)^2+(y2-y1)^2
(5, -1) and (5, 3)
√(5-5)^2+(3-(-1))^2
√0^2+4^2
√0+16
√16
4
The distance between the two points is 4.
Yes 69 is less than a right angle. A right angle must be 90 lol
