Two sides of a triangle have lengths 10 and 18. Which inequalities describe the possible lengths for the third side x?

1 answer:

7 0

Let with X is denoted the length of the third side.
For a triangle the following statements must be true:
The sum of the lengths of any two sides of a triangle is greater than the length of the third side.
This means that this inequality can be written: X<10+18 ,X<28

The answer is 43. What I did was I added all the numbers together, and since they wanted the area, and to find the area you multiply TWO numbers together, I multiplied the sum by 2 and I got 43. Hope this helps!

Aye Sir!

The observation deck is about 20 m above sea level. From the observation deck, the angle of depression of the boat is 6 degrees.

Leno4ka [110]

θ\ 6 degrees
    \
\ so the θ= 180-90-6 =84 degrees so we need to find x
20m   \ tan (84)=x/20
  ____  \ x=20 tan(84)
x x=190.287
