Well, we are told that in the beginning, it has traveled 30km vertically, so do not forget to add that on at the end.

Next it says that it traveled 40km 30 degrees from vertical, so we set up a sin equation to solve for the missing side, n:

sin(angle)= opposite/hypotenuse:

sin(30) = n/40

40sin30=n

n=20km

Then it says at an angle of 45 degrees, it goes 100km. This means that we are given the hypotenuse of a right triangle, and we need to find the side that goes up and down. We shall call this length x.

We know that the angle opposite x is 45 degrees.

So, we will use sin to solve for x:

sin(angle)= opposite/hypotenuse

sin45= x/100

100sin45=x

x=70.711km

But remember, I said not to forget about that 30km from the very beginning? So we add up all of our vertical heights:

30km + 20km+ 70.711km = 120.711km

The surface of the Salton Sea in California is 226 feet below sea level. The peak of a mountain, also in California, is 10,000 f
Ivenika [448]

Answer:

10226 ft

Step-by-step explanation:

Let x be the sea level, A horizontal imaginary line on the sea's surface.

-Given that Salton is -226 ft below this line and the mountain is 10000ft above sea. The difference between this elevetions is calculated as;

\bigtriangleup =Mountain \ Peak-Sea \ bottom\\\\=10000-(-226)\\\\=10000+226\\\\=10226

Hence, the difference between the two elevations is 10226 ft
