In the following figure find a deg,2adeg and bdeg
vampirchik [111]
From the figure. a and b are equal because the lines are parallel. The jargon is alternate interior angles are equal.

The two remote interior angles are equal to the exterior angle. That interprets to
b + 2a = 84o But b = a
a + 2a = 84o
3a = 84
a = 84/3
a = 28 <<<< answer
b = 28 <<<< answer
2a = 56 <<<< answer.

Considere the diagram below determine DHG
Veseljchak [2.6K]

9514 1404 393

Answer:

  A) ∠DHG = 96°

  B) arc EF = 134°

Step-by-step explanation:

<u>Part A</u>:

As you have shown in your work, angle DHG is supplementary to given angle FHG:

  ∠DHG = 180° -∠FHG

  ∠DHG = 180° -84°

  ∠DHG = 96°

__

<u>Part B</u>:

  ∠DHG is half the sum of arcs EF and DG.

  96° = (1/2)(arc EF + 58°) . . . . . fill in known values

  192° -58° = arc EF . . . . . . . . . . multiply by 2, subtract 58°

  arc EF = 134°

A simplified model of a particular monument is a rectangular pyramid placed on top of a rectangular prism, as shown. The volume
timama [110]

*See attachment for the simplified model of the monument

Answer:

The correct option is B. 13ft.

YES to option B. NO to A and C.

Step-by-step Explanation:

=>Given: Model of the monument consisting of a rectangular pyramid and a rectangular prism having a total volume of 66ft³.

Volume of monument = Volume of Pyramid + Volume of Prism = 66ft³

=>Dimensions of given rectangular pyramid:

base length (l) = 3ft

base width = 2ft

height of pyramid (h) = ? (h = Unknown)

Base Area (B) = l × w = 3 × 2 = 6ft²

Volume of pyramid = ⅓ × base area (B) × h = ⅓ × 6 × h

V of Pyramid = 2h ft³

=> Dimensions of the rectangular prism:

base length (l) = 3ft

base width (w) = 2ft

Height of prism (h) = 10ft

Base area (B) = l × w = 3 × 2 = 6 ft³

Volume of prism = base area (B) × height (h)

V of prism = 6 × 10 = 60 ft³

We are required to find the possible height of the monument.

Height of monument = height of pyramid + height of prism

Height of pyramid is unknown (h)

Height of prism = 10ft

Let's find the height of the pyramid using the Volume of the monument = volume of pyramid + volume of prism

Thus,

V of monument = 66 ft³

V of pyramid = 2h ft³

V of prism = 60 ft³

Therefore,

66 = 2h + 60

Subtract 60 from both sides

66 - 60 = 2h + 60 - 60

6 = 2h

Divide both sides by 2

3 = h

Height of pyramid (h) = 3ft

Height of monument = h of Pyramid + h of prism

Height of monument = 3 + 10

Height of monument = 13ft.

The correct option is B. 13ft.

YES to option B. NO to A and C.
