2x + 3x + 3x + 12 = 180° [Sum of all angles of a triangle is 180°]

=> 7 x = 180° - 12°

=> 7 x = 168°

=> x = \frac{168}{7}°

=> x = 24°

\\

? = 2x + 3x

=> 2×24° + 3×24°

=> 48° + 72°

<h3>=> 120°</h3>

HOPE IT HELPS

A supermarket needs to display 64 boxes of detergent.
Amiraneli [1.4K]
  • All the listed combination of row and boxes are correct and can be chosen from.

From the question, we are asked to find the row arrangement of a stack of boxes. Let us take a look at each one of the aforelisted answers

  • x rows with 16 boxes in each row
  • 8 rows with x boxes in each row
  • 16 rows with x boxes in each row

Since we are told that the total number of boxes to be stacked is 64, then for the first arrangement, we can deduce that the "x" is going to be 4. This is because multiplying 4 by 16 gives 64. For the second row, using the same calculation, we find that "x" is 8. And that of the third gives our "x" to be 4 as well. We can then adjudge that;

  • 4 rows with 16 boxes in each row
  • 8 rows with 8 boxes in each row
  • 16 rows with 8 boxes in each row

Bearing this in mind, we can see that each of the 3 answers fits into the requirements we are asked.

  • At least 3 rows, and at least 4 boxes in each row.

Hence, all of the options are correct.

The diameter of a circle is 10 millimeters. The circumference of the circle is 62.8 millimeters.
Vilka [71]
Well, to find a circles circumference, C=D* pi. if d =10, 10 * pi (or 3.14 for now), C= 31.4. so the answer is false. It is measuring distance as a radius instead of diameter.
