Answer:
All you have to do is use the formula for coordinates of a midpoint of a line segment. If the segment's ends are
A
=
(
x
A
,
y
A
)
and
B
=
(
x
B
,
y
B
)
, then the midpoint has coordinates:

Answer:-14
Step-by-step explanation:
(1-√-4)(-3-√-25)
[(1*-3)-(1*√-25)-(√-4*-3)-(√-4*√-25)]
(-3)-(-5)-(6)-(10)
-14
180^2 + 235^2 = (cliff base to point on bridge)^2
32400 + 55225 = 87625
so cliff base to point on bridge = sqrt of 87625.
Then notice 87625 + d^2 = (x+180)^2
since x^2 +235^2 = d^2,
substitute (x^2 + 235^2) for d^2, like this:
87625 + x^2 + 235^2 = (x+180)^2
87625 + x^2 + 55225 = x^2 + 360x + 32400
87625 + 55225 - 32400 = x^2 - x^2 +360x
360x = 110450
x = about 306.8 feet
h = x+180, so h = 486.8 feet
Remember d^2 = x^2 + 235^2, so
d^2 = 306.8^2 + 235^2
d^2 = 149354.6489
d = about 386.46 feet
