Answer: A. 1/4n - 2 = 10
Step-by-step explanation:
1/4n = One-forth of a number
-2 = Two less than
= 10 = is 10
See diagram
so we got a right triangle
so for a right triangle, when we've got legs a and b and hytponuse c then
a²+b²=c²
so the legs are 90 and 90
hytponuse is distance from home to 2nd
so
90²+90²=c²
8100+8100²=c²
16200=c²
sqrt both sides
90√2=c
