Answer:
25
Step-by-step explanation:
"y varies inversely with x" means:
y = k / x
where k is a constant.
When x = 5, y = 10.
10 = k / 5
k = 50
y = 50 / x
When x = 2:
y = 50 / 2
y = 25
68 because it is a perpendicular bisector we can assume that the angles full length is 90 degrees meaning you can just do 90-22=68
