Just wondering how I would get the area of the middle part, I have both the triangles and one square down, I just can’t get the

middle one.

The total area = Area of a right angle triangle + rectangle

The area of triangle = 1/2 x b x h

base = 11

Height = 8

Area of a triangle = 1/2 x 8 x 11

Area = 8 x 11 / 2

Area = 88/2

Area = 44 square inches

For the first rectangle

Area = Length x width

Length = 11 inches and width = 9 inches

Area = 11 x 9

Area = 99 square inches

A prism is completely filled with 3996 cubes that have edge lengths of 1/3 in.
Aleonysh [2.5K]
To answer this problem, we determine first the volume of the cubes by the equation,
                                V = e³
where V is volume and e is the length of each edge. Substituting the known value to the equation,
                             V = (1/3 in)³ = 1/27 in³
Then, to determine the volume of the prism, we multiply the calculated volume to the number of cubes. That is,
                            V (prism) = (1/27 in³)(3996 cubes) = 137.89 in³
Thus, the volume of the prism is approximately 137.89 in³.

Use the diagram and the given angle measure to find the other three angle measures
svetoff [14.1K]

By using the diagram and the given angle measure we get that:

if, m∠1 = 143°

then, m∠2 = 37°

         m∠3 = 143°

         m∠4 = 37°

What is angles?

An angle is formed when two straight lines or rays meet at a common endpoint.

What is Properties of Congruence?

  • Reflexive Property:

       For all angles A ,

        ∠A≅∠A .

       An angle is congruent to itself.

  • Symmetric Property:

        For any angles A  and  B ,

        if ∠A≅∠B , then ∠B≅∠A .

         Order of congruence does not matter.

  • Transitive Property:

        For any angles A,B,  and  C ,

        if ∠A≅∠B and ∠B≅∠C , then ∠A≅∠C .

        If two angles are both congruent to a third angle, then the first two        angles are also congruent.

I assume that, this refers to two intersecting lines which form four angles.

  • ∠1 and ∠2 are supplementary angles whose sum is 180°.                                      

         ∠1 + ∠2 = 180°

          143° + ∠2 = 180°

          ∠2 = 180° - 143°

          ∠2 = 37°.

  • ∠1 and ∠3 are vertical angles so do with ∠2 and ∠4.
  • Therefore, it is easy to find their measures because vertical angles are congruent in measure.

         It means that,  ∠1 = ∠3 =143° (properties of congruency)

         and ∠2 = ∠4 =37° (properties of congruency).
