Thread: Need some help ! newbie here !

hi i'm Jhaycian Velasquez 19 years of age an engineering student )

can u please help me out of this give me some figure

two observers who are 2 miles apart on a horizontal plane observe a balloon in a same vertical plane with them

two observers who are 2 miles apart on a horizontal plane observe a balloon in a same vertical plane with themselves. the angles of elevation are 50 degrees and 65 degrees respectively. find the height of the balloon,(a)if it is between the observers;(b)if it is on the same side of both of them.

) i hope u will help me )

Hello, Jhaycian!

Two observers are 2 miles apart on a horizontal plane.
They observe a balloon in a same vertical plane with themselves.
The angles of elevation are 50 degrees and 65 degrees respectively.
Find the height of the balloon

(a) if it is between the observers.

Code:

            C
            *
           *| *
          * |   *
         *  |h    *
        *   |       *
       *65  |      50 *
    A *-----*-----------* B
      :  x  D    2-x    :

The observers are at and :
The balloon is at ; its height is

Let

In .[1]

In .[2]

Equate [1] and [2]: .

. . . . . . . . . . . . . .

. . . . . . .

. . . . . .

Therefore: .

(b) if it is on the same side of both of them.

This is the diagram for this scenario.

Code:

                      * C
                    **|
                  * * |
                *  *  |
              *   *   |h
            *    *    |
          *     *     |
        *50    *65    |
    A *-------*-------* D
      :   2   B   x   :

Give it a try . . .

Thanks a lot for help me out
