Helene, a hiker, starts at an elevation of 27 feet above sea level and descends 32 feet during her hike to base camp. which describes the elevation of base camp?

5 feet below the sea level.

Step-by-step explanation:

Helene, a hiker starts at an elevation of 27 feet above the sea level.

Then Helene descends 32 feet that means her total elevation above the sea level will be

h = 27 - 32 = -5 feet.

Minus sign indicates that Helene is 5 feet below the sea level.

except a rational number. : )

hope this !

step-by-step explanation:

d = distance between moon and sun, which in this problem is the hypotenuse of a right triangle.  

the distance y is the side opposite to angle x in the right triangle.   use the definition of the sine function from basic trigonometry.

sin(x) = y/d ⇒

d = y/sin(x)
