Answer:
If x varies directly as y, then x=ky. y=5 and x=2.5 are substituted into x=ky to find k.
2.5=5k
k=2.5/5
k=5.
K =5 is substituted in x=ky to find y where x is 10.
x=5y
10=5y
y=10/2
y=2
You can’t really know the y value unless you’re told that they’re both directly proportional. if so, then check out the pic
Answer:
1. y = 36°
a = 9.7
2. No.. wire H to P/Q is not a tangent
