Answer:

Step-by-step explanation:

RV=VU and SW=WT ⇒ $VW=\dfrac{RS+UT}{2}$

So:

$3x+5=\dfrac{2x+15+6x-37}{2}\\\\3x+5=\dfrac{8x-22}{2}\\\\3x+5=4x-11\\^{\qquad-5\qquad-5}\\3x=4x-16\\^{-4x\qquad-4x}\\-x=-16\\^{\div(-1)\quad\div(-1)}\\x=16\\\\RS=2x+15=2\cdot16+15=32+15=47$

The number of adults = 41

The number of children = 97

Step-by-step explanation:

Let x be the number of adults and

y be the number of children

then according to the given conditions

$x+y = 138\ \ \ Eqn\ 1\\11x+4y = 839\ \ \ Eqn\ 2$

From equation 1:

x = 138-y

Putting in equation 2

$11(138-y)+4y = 839\\1518-11y+4y = 839\\1518 -7y = 839\\-7y = 839-1518\\-7y = -679\\$

Dividing both sides by -7

$\frac{-7y}{-7} = \frac{-679}{-7}\\y = 97$

Putting y = 97 in equation 1

$x+ 97 = 138\\x = 138-97\\x = 41$

Hence,

The number of adults = 41

The number of children = 97

Answer:

1011.05

Step-by-step explanation:

Let's use 3 as an example.

The angle of depression is the one directly under the ballon.

You also know that the 53 degree angle is part of a 90 degree angle.

so the angle inside the triangle directly under the balloon is 37 degrees.

You know the angle and you know the side from the balloon to the ground is 1680. This is the hypotenuse of the triangle.

So which trig function could you use to determine how high the balloon is from the ground?

SOH CAH TOA

cos 37 = a/1680

a = 1341.71
