Hello!</h2>
The asnwer is: Cos50° ≈ 0.643
<h2>
Why?</h2>
A unit circle is a cirgle with a radius equal of 1, knowing that, also know the following:
The angle is drawn passing trough the unit circle at (0.643,0.766) it means that:
So,
Cos50° ≈ 0.643
We can prove that by following the next steps:
- If it's a unit circle,here is a right triangle with hypotenuse of 1,
- We can determine the cosine of the angle by the following formula:
Therefore,
Cos(α)=49.98°≈50°
Also, if there is a right triangle, according to the Pythagorean Thorem:
Hence,
Cos50° ≈ 0.643
Have a nice day!
Answer:
Mean: Use any 5 numbers that make 25.
Median: 5
Step-by-step explanation:
For the mean you can use 2.5+2.5+2.5+7.5+10
I'm not sure about the median... If it's asking about the median for the set I used, it would be 2.5. If it's asking about the one gives, not including the zero would be 5.
Answer:
-7
Step-by-step explanation:
- The sum of all angles in a triangle will be equal to 180.
- So we add x+46+x+71+77=180*
- 2x+194=180
- 2x= -14
- x=-7
Answer:
???
Step-by-step explanation:
Ok so 4*5=20
so the area is 20meters
now lets convert 200cm to m
= 200/100=2m
now 20m/2=10
so therefore, the gardener would need 10 bags of grass seeds
hope this helped :)
