The sum of angles of a triangle is 180°, so m∠K = 180° -45° -30° = 105°.
The Law of Sines tells you
... FL/sin(∠K) = FK/sin(∠L)
Solving for FL, we get
... FL = FK·sin(∠K)/sin(∠L)
... FL = a·sin(105°)/sin(30°) = a·sin(105°)/(1/2)
... FL = 2a·sin(105°) ≈ 1.93185a
Answer:
Step-by-step explanation:
You need to analize the information given in the exercise.
By definition, there are 360 degrees in a circle.
In this case, you know that the Central angle in degrees of the given sector of the circle is the following:
And the area of that sector is this one:
Then, you need to calculate the number of sectors in that circle.
In order to do it, you have to divide 360 degrees by the central angle of that sector. So, you get:
Knowing that there are 8 sectors in the circle, you need to multiply the area of the sector given in the exercise by 8, in order to calculate the area of the circle.
Therefore, this is (Using ):
Answer:
I would say 100 since 256.78 is closer to 100 then 1000 or 10
Step-by-step explanation:
Ok I just have the phone number for my dad to go it
The answer is 830,000 because if the 4 would be above 5 the three would become 4.
