4πrsquare= 2πrsquare+2πrh
2πrsquare=2πrh
R=h
So h=16/2=8mm
Answer:
A.S.A congurency.
please mark me brainliest and follow me my friend.
Perpendicular means that it has a slope that is the reciprocal of the original, and parallel means that the slopes are the same.
We are given
v = 18 m/hr west
θ1 = 285°
θ2 = 340°
After 1 hours, the distance traveled by the ship is
dv = 18 mi
The distance between the ship and the lighthouse is
d = 18 / cos 340
Solve for d<span />
