Answer:

Step-by-step explanation:
We are given a triangle
whose sides are
a=12
b=8
c=13
Since, c is largest among them
So, angle C must be largest angle
we can find angle C
we can use law of cosine formula

now, we can plug values


now, we can find angle
we get

Using the Pythagorean triples, one side is 3 units long, one side is 4 units long, and one side is 5 units long. To find the area of a right triangle, multiply length times width. Then divide total by two.
So,
(3•4)/2= 6 units
After scaling units, you should get 24 units.
Step 1.
Calculate measure of angle α:

Step 2.
Calculate what fraction of the angle 360° is the angle α:

Step 3.
Calculate the circumference of the Earth (circle):

Step 4.
The length of arc is equal 1/40 of the circumference:


<h3>Answer: A) 628 miles</h3>
Answer:
Lin = 8.2 m/s x 25 s =<u> 205 m </u> (<em>Finish Point)</em>
Elena = V = 250 m / 28 s <u>V = 8.93/s </u> (<em>Velocity</em>)
Diego = -8.1 m/s x 32 s =<u> -259.2 meters</u> (<em>Finish Point</em>)
Andre = V = -285 m /35 s V= -8.14ms (<em>Velocity</em>)
Step-by-step explanation:
