NGC is a hot air balloon in the sky from her spot on the ground. The angle of elevation from Angie to the balloon is 40°. If she

Goshia [24]

Answer:

The distance from hot air balloon to the ground $AC=50.1457 ft$ .

Step-by-step explanation:

Labelled diagram of given scenario is shown below.

Given that,

An angle of elevation of Hot air balloon by Angie is $40$ °.

When she stepped back $200 ft$ then angle of elevation was $10$ °.

Height of Angie is $5.5 ft$ .

To find: How far off the ground is a hot air balloon.

So, from figure

Height of Angie $(BC) = 5.5ft$

In triangle Δ $ABD$ ,

⇒ $tan {40\si {\degree}} = \frac{AB}{BD}$

⇒ $AB = tan (40) \times BD$ ....................(1)

Now, In triangle Δ $ABE$

⇒ $tan (10)= \frac{AB}{200+BD}$

⇒ $AB = tan(10)\times (200+BD)$

Here, substituting the value $AB$ from Equation (1) we get,

$tan(10)\times (200+BD)= tan(40)\times BD$

$tan(10)\times 200+tan(10)\times BD= tan(40)\times BD$

⇒ $BD\times (tan(40)-tan(10))=tan(10)\times 20$

⇒ $BD\times 0.6628 = 35.2654$

⇒ $BD = \frac{35.2654}{0.6628} =53.2067 ft$

Now, finding the value of $AB$ from equation (1)

$AB= tan(40)\times 53.2067=0.8391\times 53.2067$

$AB=44.6457 ft$

Therefore Length of $AC= AB+BC$ = $(44.6457 + 5.5) ft$

$AC=50.1457 ft$ .

Hence,

The distance from hot air balloon to the ground $AC=50.1457 ft$ .

Five pennies, 3 dimes, and 4 quarters are placed in a bag. What is the probability of selecting a penny and then a dime, given t

VashaNatasha [74]

There are 12 coins in the bag. For the first case, the probability that a penny is selected from the bag is 5/12 because there are 5 pennies in the bag. Also, the next one is 3/11. Multiplying the probabilities,
(5/12)(3/11) = 8/121

Answer:

A quadrilateral become square if all the sides joining the co-ordinate of quadrilateral is equal

Step-by-step explanation:

Here the given co-ordinate of quadrilateral are

G (3, -1) O(1, -6)

L(-4, -4) F(-2, 1)

Line GF = $\sqrt{(3+2)^2+(-1-1)^2}$

GF = $\sqrt{29}$

Similarly for line OG, OL, FL

OG = $\sqrt{(1-3)^2 +(-6+1)^2$

OG = $\sqrt{29}$

OL = $\sqrt{(-4-1)^2+(-6+4)^2}$

OL = $\sqrt{29}$

And

FL = $\sqrt{(-4+2)^} +(-4+1)^2$

FL = $\sqrt{29}$

all the sides of quadrilateral GF, OG, OL, FL all equal to $\sqrt{29}$

As all the sides are equal so quadrilateral become square Answer
