Altitude: An airplane was at a cruising altitude, then descended 2000 feet. If the airplane is at 18,000 feet now, what was the cruising altitude?

20000 feet

Step-by-step explanation:

18000+ 2000 = 20000 feet

20,000 feet is the cruising altitude.

Step-by-step explanation:

If they just descended 2,000 feet, and are now at 18,000, then we need to add back the 2,000 to get to the original alitutude. Once you have done this (added the two numbers), you will get 20,000. Hopefully this helps!

x = 17

step-by-step explanation:

in the given figure, two triangles are inscribed in a circle where ∠bae ≅ ∠dae which makes the side be and de equal so we can write it as:

3x - 24 = x + 10

solving this equation for x to get:

3x - x = 10 + 24

2x = 34

x = 34/2

x = 17

therefore, the value of x = 17.

the first one, all those points on the line just make a strait line.
