Answer:

36 inches

Step-by-step explanation:

if you unfold the triangular prism and find the area of each individual shape, all you have to do is add them up:

Area Of Rectangle = WL

Area Of Triangle = 1/2(HB)

5x2=10

4x2=8

3x2=6

(4x3)1/2=6x2=12

10+8=18+6=24+12=36

Answer:

1. transversal: (of a line) intersecting a system of lines.

2. acute angle: Acute angles measure less than 90 degrees. Right angles measure 90 degrees. Obtuse angles measure more than 90 degrees. Learn about angles types and see examples of each.

3. alternate extirior angles: When two lines are crossed by another line (called the Transversal): Alternate Exterior Angles are a pair of angles on the outer side of each of those two lines but on opposite sides of the transversal.

4. congruent: in agreement or harmony.

5. congruent figures: Congruent figures are geometric figures that have the same shape and size. That is, if you can transform one figure into another figure by a sequence of translations , rotations , and/or reflections , then the two figures are congruent.

6. isosceles triangle: In geometry, an isosceles triangle is a triangle that has two sides of equal length. Sometimes it is specified as having exactly two sides of equal length, and sometimes as having at least two sides of equal length, the latter version thus including the equilateral triangle as a special case

7. obtuse angle: An obtuse angle ...” ... An obtuse angle has a measurement greater than 90 degrees but less than 180 degrees. However, A reflex angle measures more than 180 degrees but less than 360 degrees. So, an angle of 190 degrees would be reflex.

8. right angle: an angle of 90°, as in a corner of a square or at the intersection of two perpendicular straight lines.

9. remote interior angle: Remote interior angles are angles that don't share a vertex or corner of a triangle with the exterior angle. The measure of the exterior angle equals the sum of the two remote interior angles.

10. same-side interior angles:Same side interior angles are two angles that are on the same side of the transversal and on the interior of (between) the two lines. Same Side Interior Angles Theorem: If two parallel lines are cut by a transversal, then the same side interior angles are supplementary.

11. corresponding angles: When two lines are crossed by another line (which is called the Transversal), the angles in matching corners are called corresponding angles. Example: a and e are corresponding angles. When the two lines are parallel Corresponding Angles are equal.

12. corresponding parts: corresponding parts. Sides or angles that occupy the same relative positions in similar polygons. congruent triangles. 2 triangles are congruent if and only if all pairs of corresponding sides and angles are congruent.

13. equilateral angle: In geometry, an equilateral triangle is a triangle in which all three sides have the same length. In the familiar Euclidean geometry, an equilateral triangle is also equiangular; that is, all three internal angles are also congruent to each other and are each 60°.

14. exterior angle: 1 : the angle between a side of a polygon and an extended adjacent side. 2 : an angle formed by a transversal as it cuts one of two lines and situated on the outside of the line.

15. scalene triangle: A scalene triangle is a triangle in which all three sides have different lengths. Also the angles of a scalene triangle have different measures. Some right triangles can be a scalene triangle when the other two angles or the legs are not congruent.

16. similar figures: Two figures are said to be similar if they are the same shape. In more mathematical language, two figures are similar if their corresponding angles are congruent , and the ratios of the lengths of their corresponding sides are equal. This common ratio is called the scale factor .

17. striaght figures: A line that does not curve. In geometry a line is always straight (no curves).

18. theorem: a general proposition not self-evident but proved by a chain of reasoning; a truth established by means of accepted truths.

Answer: C

Step-by-step explanation: 3 2/5 - 5/2

Answer:

A) |-6| + |3|

Step-by-step explanation:

Since the y-coordinates are the same, we need to find the distance between -6 and 3. This would thus be equal to |-6|+|3| making A the correct answer.

Answer:

Ariana is correct. The difference in the price is $3. So the percentage that you saved has to equal $3.

Step-by-step explanation:

$15.00 x .10 or 10% = $1.50

$1.50 x 2 will give you 20%

$1.50 x 2 = $3.00

$15.00-$3.00 = $12.00

Answer:

90degrees

Step-by-step explanation:

43+x = 90

x= 90-43

x= 47

.........................

Answer:

x=11

Step-by-step explanation:

First Distribute 11 to 9 and -2x

Then distribute the negative to 12x and 11

Then calculate like terms

-22x + 12x = -11 -99 which comes out to -10x=-110

Then divide each side by -10

Your answer will then be x=11

Answer:

452.16 cm²

Step-by-step explanation:

3.14 × 12² = 452.16 cm²

Answer:

452.16

Step-by-step explanation:

Comes down to knowing the Area of a Circle formula- A = πr².

A = area

r = radius, in your case, 12

A = π(12)² = 452.16cm²
