In a trapezoid, two opposite sides are parallel and are called bases.
In this trapezoid, the top and bottom sides are parallel and are the bases.
The right side that intersects both bases is a transversal.
When parallel lines are cut by a transversal, same-side interior angles are supplementary. The measures of supplementary angles add to 180 deg.

x + 72 = 180

x = 180 - 72

x = 108 deg

Identify the volume of the composite figure rounded to the nearest tenth.
Verdich [7]

Answer:

  (c)  115.2 ft³

Step-by-step explanation:

The volume of a composite figure can be found by decomposing it into figures whose volumes are easy to compute. Here, the figure can be nicely represented as a cube and a square pyramid.

__

<h3>Cube</h3>

The volume of the cube on the left is given by ...

  V = s³

  V = (4.2 ft)³ = 74.088 ft³

__

<h3>Pyramid</h3>

The volume of the pyramid on the right is given by ...

  V = 1/3Bh . . . . . where B is the area of the square base

  V = 1/3(s²)h = (4.2 ft)²(7 ft) = 41.16 ft³

__

<h3>Total</h3>

The volume of the composite figure is the sum of these volumes:

  cube volume + pyramid volume = 74.088 ft³ +41.16 ft³ = 115.248 ft³

The volume of the composite figure is about 115.2 ft³.

Hullan's age is three times Thomas's age. The sum of their ages is 92. What is Thomas's age?
Ksju [112]

Answer: 23

Step-by-step explanation: You can start by setting this up as an equation like so,

X + 3(X) =92 where x is Thomas’ age and the 3x indicates Hullans age being 3 times greater than Thomas.

Combine the x’s

4(x) = 92

Divide by 4 X = 92/4

92/4 = 23, x = 23
