help please!! Mark the following triangles so that they are congruent by the Side-Side-Side Postulate
Ivenika [448]

Hi!

If you want to show these are congruent, you make a single line through each of the sides. Just do this for both of the triangles.

See the screenshot for example

Hope this helps! :0)

A factory produces widgets whose length must be within 1.5 mm of an ideal length of 47 mm. A factory supervisor wants to mark ru
Nat2105 [25]

Using absolute value, it is found that:

  • The situation is described by the following equation: |l - 47| = 1.5
  • The markings should be between 45.5mm and 48.5mm.

---------------------------

The definition of the <em>absolute value function</em> is as follows:

|x| = x, x \geq 0

|x| = -x, x < 0

----------------------------

The length should be set to 47mm with an allowance of 1.5mm, which means that <u>the absolute value of the difference between the length and 47 should be 1.5</u>, thus:

|l - 47| = 1.5

----------------------------

The solutions are:

l - 47 = -1.5 \rightarrow l = 45.5

l - 47 = 1.5 \rightarrow l = 48.5

The markings should be between 45.5mm and 48.5mm.
