Write a list of steps that are needed to find the measure of ∠b

Answers

Answer 1

Answer:

The list of the steps should be explained below:

The calculation is as follows:

Triangle has 3 angles, A, B, C.

The total interior angle of a triangle is 180.

Now

180 = A + B + C

180 = 72 + B + 113

180 = B + 185

B = 180 - 185

B = -5

So, the above proves that the figure is not a triangle because angle B is negative

Answer 2

Answer:

Answer:

${\angle}ABC=41^(\circ)$

Step-by-step explanation:

From, the given figure, it is given that ${\angle}BAC=72^(\circ)$ and ${\angle}BCD=113^(\circ)$ .

Using the exterior angle property in ΔABC, we have

${\angle}ABC+{\angle}BAC={\angle}BCD$

⇒ ${\angle}ABC+72^(\circ)=113^(\circ)$

⇒ ${\angle}ABC=113^(\circ)-72^(\circ)$

⇒ ${\angle}ABC=41^(\circ)$

Therefore, the measure of ${\angle}B$ is $41^(\circ)$ .

10. Make Sense and Persevere The flag of theBahamas includes an equilateral triangle. The
perimeter of the triangle is P= 3s, where s is
the side length. Solve for s. Use your formula to
find the dimensions of the flag in feet and the
area in square feet when the perimeter of the
triangle is 126 inches.

Answers

Answer:

$s=(P)/(3)$
Dimensions of the flag:

$lenght=6.65\ ft\n\nwidth=3.5\ ft$

Area of the flag: $23.275\ ft^2$

Step-by-step explanation:

The missing figure of the exercise is attached.

We know that the perimeter of the triangle is given by:

$P= 3s$

Where "s" is the side lenght of the triangle.

Solving for "s", we get:

$s=(P)/(3)$

Therefore, if the perimeter of the triangle is 126 inches, its side length is:

$s=(126\ in)/(3)\n\ns=42\ in$

Since $1\ ft=12\ in$ , we know that "s" in feet is:

$s=(42\ in)((1\ ft)/(12\ in))=3.5\ ft$

The area of a rectangle can be calculated with this formula:

$A=lw$

Where "l" is the lenght and "w" is the width

We can observe in the figure that the lenght and the width of the flag are:

$l=1.9s\nw=s$

Then, the dimensions of the flag are:

$l=1.9(3.5\ ft)=6.65\ ft\nw=3.5\ ft$

And the area is:

$A=(6.65\ ft)(3.5\ ft)=23.275\ ft^2$

Kareem has 4 sweaters, 6 shirts, and 3 pairs of slacks. How many distinct outfits, each consisting of a sweater, a shirt, and a pair of slacks, can Kareem select?

Answers

The number of the distinct outfit is 30 each consisting of a sweater, a shirt, and a pair of slacks that can Kareem select.

What is a numerical expression?

A numerical expression is algebraic information stated in the form of numbers and variables that are unknown. Information can is used to generate numerical expressions.

We have been given that Kareem has 4 sweaters, 6 shirts, and 3 pairs of slacks.

To determine the number of distinct outfits, each consisting of a sweater, a shirt, and a pair of slacks, can Kareem select.

Add 4 sweaters and 6 shirts and that should add up to 10 in total, then times 10 sweaters/shirts by 3 slacks to get 30 as a grand total.

Therefore, the number of the distinct outfit is 30 each consisting of a sweater, a shirt, and a pair of slacks that can Kareem select.

Step-by-step explanation:

Find the area of each shape by decomposing it into smaller shapes, and combining their area.

Answers

you can divide this picture into 2 pieces, 1 rectangle and 1 triangle.

To find the rectangle, since the opposite sides are equal to each other, the width=6.

the length is 8.

to find the area, use the formula

A = lw

A= 8 x 6

A = 48 units square

that's for rectangle.

for the triangle, use the formula

A = h x b / 2

height=10-6 = 4

base is 8 because the opposite sides are equal in rectangle.

Substitute height and base in the formula.

A= 4 x 8 / 2

A= 32/2

A=16 units square

That's the area of triangle.

Now, you can add the area of rectangle and triangle.

Total area = area of rectangle + area of triangle

A = 48 + 16

A = 64 units square
