To express a number in one unit as an equivalent value of another unit

ddd [48]

A conversion factor is a number used to change one set of units to another, by multiplying or dividing. When a conversion is necessary, the appropriate conversion factor to an equal value must be used. For example, to convert inches to feet, the appropriate conversion value is 12 inches equal 1 foot.

Answer:

12. (x, D, E, F) = (8, 38°, 75°, 67°)

13. (x, P, Q, R) = (13, 126°, 30°, 24°)

Step-by-step explanation:

The sum of angles in a triangle is 180°. We choose to write the equations assuming all measures are degrees.

12. (5x -2) +(9x +3) +(11x -21) = 180

25x = 200 . . . . . . . add 20, simplify

x = 8 . . . . . . . . . divide by 25

Then the angle measures are ...

∠D = 5(8) -2 = 38°

∠E = 9(8) +3 = 75°

∠F = 11(8) -21 = 67°

13. (10x -4) +(4x -22) +(x +11) = 180

15x = 195 . . . . . . . . . . add 15, simplify

x = 13 . . . . . . . . . divide by 15

Then the angle measures are ...

∠P = 10(13) -4 = 126°

∠Q = 4(13) -22 = 30°

∠R = 13 +11 = 24°

I don't get the subject of congruent triangles. How do I figure out if there's not enough information to know if it is congruent

babymother [125]

Answer:

Okay, there are many ways to find if a triangle is congruent.

Let's start with some different terminology.

For the sake of simplicity let us say that S stands for when a side is congruent for both triangles and A stands for when an angle (<) is congruent between both the triangles as well.

So, you need to memorize some rules. If you find that 2 triangles are congruent in the sense of; SSS, SAS, AAS, SAA, and ASA. One thing to remember is that Angle Side Side isn't congruent and is called <em>Donkey Theorem</em>. This theorem only works for right triangles.

One way to know if your triangle isn't congruent is if you can find a part of the triangle that is different.

I know that wasn't the best explanation but I hope it helped anyhow. :)

Compare the numbers by entering <, >, or =.

Andrew [12]

Your answer would be:
596.64 = 596.640
Reasoning= If you just take away the zero from 596.640 you would have the same answer as 596.64. Now if you add a zero to 596.64 you still would have the same answer, therefore they are equal.
Hope this helps! (:
