Right Triangles and the Pythagorean Theorem
The Pythagorean Theorem, a2+b2=c2, a 2 + b 2 = c 2 , can be used to find the length of any side of a right triangle.
The side opposite the right angle is called the hypotenuse (side c in the figure).
Answer:
-3/12
Step-by-step explanation:
"<em>The distance around a circle"</em> = Circumference
Circumference = 3.14 * diameter
3900 * 3.14 = 12246
The circumference (distance around the crater) is equal to 12,246 feet
Make a systems of equations:
11x+13y=209
x+y=19
