Tomtit [17]

Answer:

Total tape used by marge is 6 inches .

Step-by-step explanation:

As given

marge cut 16 pieces of tape for mounting pictures on poster board.

Each\ piece\ of\ tape\ was\ \frac{3}{8}\ inch\ long.

Total tape marge uses = Number of pieces × Each piece length

Total\ tape\ marge\ uses = \frac{16\times 3}{8}

Total tape marge uses = 2 × 3

                                      = 6 inches

Therefore the total tape used by marge is 6 inches .

Using distance formula :

  • \sqrt{(x_2 - x_1) {}^{2}  + (y_2 - y_1) {}^{2} }

  • \sqrt{(8 - ( - 4)) {}^{2}  + ( - 7 - ( - 2)) {}^{2} }

  • \sqrt{(12) {}^{2} + ( - 5) {}^{2}  }

  • \sqrt{144 + 25}

All the pictures are in order for every question
ivanzaharov [21]

Answer:

  1. C.) obtuse triangle
  2. 39°
  3. 167°
  4. D.) 111°

Step-by-step explanation:

1. The sum of angles in a triangle is 180°. The sum of the given angles is less than 90°, so the remaining angle must be more than 90°. When the largest angle is more than 90°, it is an obtuse angle. A triangle with an obtuse angle is classified as obtuse.

__

2. The sum of the interior angles is 180°, so we have ...

  x° +39° +102° = 180°

  x° = 39° . . . . . . . . . . . subtract 141°

__

3. The third interior angle is the supplement to the sum of the given interior angles. Likewise, x° is the supplement to the third interior angle, so its value is the same as the sum of the two given interior angles. (The rule is often stated as "an exterior angle is equal to the sum of the remote interior angles.")

  x° = 130° +37°

  x° = 167°

__

4. Same deal as problem 3:

  x° = 75° +36°

  x° = 111°
