Answer:

Step-by-step explanation:

4A Area is 40. The area is the length times the width giving you an answer of 40 sq in.

4A Perimeter is is 2L+2W. Multiply the length by 2 then the width by two and add them together this gives you 8+20 which is 28 inches.

The difference of 2 numbers is 3 and their sum is 25. What are the numbers? 10 and 15 14 and 11 11 and 13 13 and 12

vagabundo [1.1K]

Let the two numbers be x and y

As given, the difference of two numbers is 3, so

$x-y=3$ or $x=3+y$ ....(1)

And their sum is 25, so

$x+y=25$ .....(2)

Putting x=3+y in equation (2)

$3+y+y=25$

$2y=22$

$y=11$

As, x+y=25

$x+11=25$

$x=14$

So the two numbers are = 14 and 11

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 $AC=50.1457 ft$ .
