Answer:

32

Step-by-step explanation:

Given that G is the centroid of triangle AEC, the perimeter of triangle AEC is: A. 32 units

To understand how to derive the perimeter of [tex]\triangle AEC[/tex], recall the following related to centroid of a triangle in reference to the image in the attachment below:

Also, note that:

We're going to apply the above stated facts to solve the problem given since we are told that G is the centroid of the isosceles [tex]\triangle AEC[/tex]:

G = centroid  (given)

AB = 6 units (given)

FA = 5 units (given)

EA = EC (equal sides of isosceles triangle)

EF = FA = 5 units

EA = EF + FA

EA = 5 + 5

EA = 10 units

EC = EA (equal sides of isosceles)

EC = 10 units

AB = CB = 6 units

AC = AB + CB

AC = 6 + 6

AC = 12 units

Perimeter of triangle AEC = AC + EA + EC

Perimeter of triangle AEC = 12 + 10 + 10 = 32 units

Therefore, given that G is the centroid of triangle AEC, the perimeter of triangle AEC is: A. 32 units

Step 1: Write the equation of variation

Step 2: Solve for k or the constant of proportionality

Step 3: Solve for x

Answer:

x = 6.0

Step-by-step explanation:

Given:

Line AB is the hypotenuse

50.1 degrees is an angle

90 degrees is a right angle

Line CB is x and is opposite to the 50.1 degree angle

Line AC is 5 and is adjacent to the 50.1 degree angle

We know we have angles of 50.1 degrees and 90 degrees

We could find the third angle by doing 180 = 50.1 + 90 + a; a = 39.9 degrees

Sin(angle) = Opp/Hyp, Cosine(angle) = Adj/Hyp, Tan(angle) = Opp/Adj

We know the adjacent length, degree of angle, and are looking for the opposite side; therefore, we can use tan(angle) = opp/adj

tan(50.1) = x/5

x = 5.9979

or

tan(angle) = opp/adj

tan(39.9) = 5/x

x = 5.9979

Round to the nearest tenth:

x = 6.0

Area of triangle

a = 6 ft + 2 ft + 2ft = 10 ft

h = 12 ft

½ * 10 ft * 12 ft = 60 sq ft

Area of square :

a = 6 ft

6 ft * 6 ft = 36 sq ft

Area of this figure :

60 + 36 = 96 sq ft

Answer:

156 ft

Step-by-step explanation: (This does not seem to be in scale)

1. Split into one triangle and one square

2. Find triangle area

12 * 10 = 120 ft

3. Find square area

6 * 6 = 36 ft

4. Area = Atriangle + Asquare

120 + 36 = 156 ft

Answer: t does sound logical that an only child may be more inclined to have a pet than children in larger families. However we haven’t located any statistics that support that thought.

Our own dad was a single child and did have a dog while growing up. Times were tough back in the those days 1920s to 1945 so he couldn’t have a lot of pets growing up. During WWll he adopted a dog on Siapan and smuggled her home on the ship with him when the war was over.

Growing up he always dreamed of raising dogs, but ended up raising three kids instead. The first born, a boy, loved cats but never had one of his own until he was grown up and had a place of his own. The reason he didn’t have a pet of his own as a child was because 4 years after he was born his twin sisters entered.

We hit the ground with an insatiable need to interact with animals of all kinds. Sure we had each other for companionship but some people are just born with a great need to converse with other species. From the time we entered the household all pets became ours.

As far as statistics go, they do find that families with children are more likely to have pets. It just doesn’t stipulate how many children are in the family.

One of the interesting finds though is that the percentage of childless families are increasing but pet ownership is continuing to grow as well.

Step-by-step explanation:

Answer:

Only children do have more pets because it's something to do. If your class has a mix of only children and people with siblings then you would have enough information.

Answer:

x=23

y=15

Step-by-step explanation:

Using the triangle interior theorem,

All three interior angles of a triangle add up to 180.

So that means angle x+23+134=180

Angle x=23

So x=23

Since two angles have the same measure, that means there are two sides that have same measure. Using the converse of base angles theorem,

If two angles are congruent, then the sides opposite of those angles are congruent.

Since the given angle 23 is opposite of side y and our missing angle (which is 23) is opposite of the side that measures 15.

Side y measures 15.

This triangles is a obtuse isoceles triangle.

Answer: 12

Step-by-step explanation:

Answer:

10 in

Step-by-step explanation:

This question can be solved with a proportion. 12 is to 8 as 15 is to x since the triangles are congruent. So solve 12/8=15/x. Then cross multiply to get x=10.
