Answer:

  • D. 146°

Step-by-step explanation:

<u>Arcs in the circle sum to 360°</u>

  • Arc AB = 2*∠C = 2*(48°) = 96°
  • Arc BC = 138° - given
  • Arc AC = 360° - (96° + 118°) = 146°

A rhombus is cut along the diagonals to make four triangles. Which three statements are correct for any rhombus? 1) All four tri
Nikolay [14]

Answer:

1). All four triangles are right-angled.

3.) All four triangles are congruent.

4) Area of a rhombus = 4 x area of one triangle.

Step-by-step explanation:

If a rhombus is cut into four triangles using diagonals, the three statements that would apply to any rhombus would be that 'all those four triangles would be right-angled,' 'the triangles would be congruent to one another,' and 'area of one triangle * 4 would be equal to the area of the rhombus.'

As we know, the diagonals bisect one another in a rhombus at 90° and the angles opposite to one another are equal. This <u>proves that all four triangles constructed through the diagonals would be ≅ through SSS congruency and perpendicular to one another because the corresponding edges of the congruent triangles are also ≅</u> . Since the rhombus is divided into four equal parts, the area of one triangle into four would be equals to the area of the rhombus. Thus, <u>options 1, 3, and 4</u> are the correct answers.

5: Answer the questions completely: Jordan has a new puppy. She wants to put a fence around part of her yard to cover an area of
irga5000 [103]

Given that Jordan has a new puppy and she wants to put a fence around part of her yard to cover an area of 200 square feet.

Now we have to find what dimensions (length x width) should she make the rectangular area. None of the length or width are given so there can be lots of answers.

Since area is rectangular and we know that rectangle has different value of length and width so we just need to find two factors of given area 200 square feet.

For example 20 times 10 is 200.


So the dimension of the rectangular area will be:

Length = 20 feet and width = 10 feet


Now perimeter of the rectangle is given by formula:

Perimeter = 2(length+width) = 2(20+10)=2(30)=60


Hence perimeter is 60 feet.
