Answer: The correct option is 1, i.e., SSS.

Explanation:

It is given that in triangle ABC the line CM bisects AB. The side AC=BC. In triangle ACM and BCM,

AM = BM (CM bisects AB)

CM=CM (common side)

AC= BC (given)

Since three sides of triangles are equal.

According to SSS rule of congruence theorem, two triangles are congruent if all the corresponding sides of the triangles are equal.

So by SSS rule of congruence theorem, we can conclude that the triangles ACM and BCM are congruent.

The correct option is first, i.e., SSS rule.

We can use the SSS congruence theorem to prove that the two triangles in the attached figure are congruent. The SSS or side-side-side theorem states that each side in the first triangle must have the same measurement or must be congruent on each of the opposite side of another triangle. In this problem, for the first triangle, we have sides AC, CM, AM while in the second triangle we have sides BC, CM, and BM. By SSS congruent theorem, we have the congruent side as below:
AC = BC
CM = CM
AM = BM

The answer is SSS theorem.

What is the partial derivative of a given function

Marizza181 [45]

Partial differentiation of a function with more than one variables refers to its derivative being taken with respect to one of those variables, while the rest being held as a constant.

An example is the volume of a cylinder given by:
$V(h, r) = \pi r^{2}h$

The volume requires two variables in order to work out the volume, namely the radius and the height.

Using partial differentiation, its partial derivative can become:
$\frac{\partial V}{\partial r} = 2\pi rh$

This symbol is used in place of the derivative symbol, in order to distinguish total derivatives and partial derivatives.

Evaluate x y when x = 4/5 and y = 1/3. what would the fraction or mixed number be?

Alex777 [14]

X = 4/5
y = 1/3
x+y = 4/5 + 1/3
x+y = 12/15 + 5/15
x+y = 17/15
