Answer I believe that the answer is 1/36.
Step-by-step explanation: I just toke the test and got it right.
The triangle given above is a scalene triangle as non of its given sides are equal. To determine the area of the triangle, we use the Heron's formula which is expressed as below,
A = sqrt ((s)(s - a)(s - b)(s - c))
where a, b, and c are the lengths of the sides and s is the semiperimeter ((a+b+c)/2)
The area of the triangle can also be computed through the equation, A = rs
where r is the radius of the inscribed circle. Equating both areas,
A = sqrt ((s)(s-a)(s-b)(s-c)) = rs
Divide the equation by s,
r = sqrt ((s)(s-a)(s-b)(s-c)) / s
Solving for s,
s = (12+14+16)/2 = 21
Substituting to the equation for r,
r = sqrt ((21)(21-12)(21-14)(21-16)) 21
r = sqrt 15
r = 3.87
<em>ANSWER: r = 3.87</em>
I am extremely bad at math and I am trying to help other to ask a question, but I personally think C
You multiply by 2 because if you take any number let's say 15, 15x 6 is 90 1/3 of 90 is 30 and 15 is half of thirty. this works with all numbers so the answer is dilate by a scale factor of 2.
