40×28= the answer is 1,120 eggs that he counted
Answer:
The angle will be "48.7°".
Step-by-step explanation:
In ΔTBO, the given values are:
TB = 6,000 feet
BO = 9,000 feet
Now,
To find the angle,
⇒ 
On putting the estimated values, we get
⇒ 
⇒ 
⇒ 
⇒
As x decreases y also decreased
Start by writing the system down, I will use
to represent 

Substitute the fact that
into the first equation to get,

Simplify into a quadratic form (
),

Now you can use Vieta's rule which states that any quadratic equation can be written in the following form,

which then must factor into

And the solutions will be
.
Clearly for small coefficients like ours
, this is very easy to figure out. To get 5 and 6 we simply say that
.
This fits the definition as
and
.
So as mentioned, solutions will equal to
but these are just x-values in the solution pairs of a form
.
To get y-values we must substitute 3 for x in the original equation and then also 2 for x in the original equation. Luckily we already know that substituting either of the two numbers yields a zero.
So the solution pairs are
and
.
Hope this helps :)
