Midpoint formula
mid of (x1,y1) and (x2,y2) is
so
(22,15)=
therefor
22=
and
15=
slv each
22=
times both sides by 2
44=18+x1
minus 18 both sides
26=x1
15=
times both sides by 2
30=6+y1
minus 6
24=y1
the other point is (26,24)

Answer:
Step-by-step explanation:
22.5 degrees is half of 45 degrees (special angle for which we know exactly the value of all three basic trigonometric functions (sine, cosine, and tangent).
So we start recalling the formula for tangent of a half angle:
We need just the values of:
and of
to answer the question. Then, we use those values in the original formula for tangent of a half angle:
