In Triangle XYZ, A is the midpoint of XY, B is the midpoint of YZ, and C is the midpoint of XZ.
1 answer:
Answer:
24
Step-by-step explanation:
We have the theorem that if we join the midpoints of two sides of a triangle then the line so formed will be half of the third side of the triangle.
So, here in this case in triangle XYZ, A is the mid point of XY and B is the mid point of YZ,
Hence, Segment AB = Half of segment XZ =
Similarly, Segment BC = Half of segment XY = Segment AY =7
{Since, Segment AY = Half of segment XY}
And again, Segment CA = Half of segment YZ = Segment BZ = 8
So, the perimeter of triangle ABC is = AB + BC + CA = 9 + 7 + 8 = 24. (Answer)

First, the values of 2sqrt(3) or 3sqrt(3) are not even twice the length of the given base, 3.
Next, I would say that 6 is the better answer than 12, assuming that the triangle is”drawn-to-scale”.
Finally, I think the hypotenuse is 6.

By definition of the derivative,
We have
and
Combine these fractions into one with a common denominator:
Rationalize the numerator by multiplying uniformly by the conjugate of the numerator, and simplify the result:
Now divide this by <em>h</em> and take the limit as <em>h</em> approaches 0 :
3.1.1.
Differentiate one term at a time:
• power rule
The last two terms are constant, so their derivatives are both zero.
So you end up with
