A triangle with two angles measuring 45⁰ and 92⁰ is an obtuse scalene triangle. The answer is A.

A triangle is a two-dimensional shape that has three sides and three angles. The sum of its interior angles is 180⁰.

If two angles of a triangle have measures 45⁰ and 92⁰, solving for the third angle

180⁰ = 45⁰ + 92⁰ + third angle

third angle = 43⁰

If a triangle has an angle greater than 90⁰, then it is an obtuse triangle.

If a triangle has angles less than 90⁰, then it is an acute triangle.

If a triangle has an angle equal to 90⁰, then it is a right triangle.

An isosceles triangle is a triangle with two congruent sides and congruent base angles (2 angles are equal).

An equilateral triangle is a triangle with all three sides equal and all three angles are of equal measures.

A scalene triangle is a triangle with no sides are equal and no angle are equal also.

Since our triangle has 3 unique angles: 43⁰, 45⁰, and 92⁰, with one angle greater than 90⁰, then it is an obtuse scalene triangle.

The equivalent of the given expression ( (4 1/2)x - 3 ) + ( -2 + (1 3/4)x ) is (6 1/4)x - 5.

Given the expression in the question;

( (4 1/2)x - 3 ) + ( -2 + (1 3/4)x )

First, convert the mixed fractions into an improper fractions.

( (4 1/2)x - 3 ) + ( -2 + (1 3/4)x )

( (4×2 + 1/2)x - 3 ) + ( -2 + (1×4 + 3/4)x )

( (8 + 1/2)x - 3 ) + ( -2 + (4 + 3/4)x )

( (9/2)x - 3 ) + ( -2 + (7/4)x )

Now, remove the parenthesis and collect like terms

(9/2)x - 3 + -2 + (7/4)x

(9/2)x + (7/4)x - 3 - 2

9x/2 + 7x/4 - 5

Now, add the two fractions containing x

(9x × 4)+(7x × 2)/8 - 5

( 36x + 14x )/8 - 5

50x/8 - 5

(50/8)x - 5

(25/4)x - 5

Convert 25/4 into an improper fraction

(6 1/4)x - 5

Therefore, the equivalent of the given expression ( (4 1/2)x - 3 ) + ( -2 + (1 3/4)x ) is (6 1/4)x - 5.

The perimeter of the triangle ABC is approximately equal to 35.633 units.

In this problem we find the locations of the three vertices of the triangle and from which we have to calculate the length of each of the three sides. The perimeter is the sum of the three lengths. First, determine the vectors of each side:

AB = (2, - 9) - (- 3, 2)

AB = (5, - 11)

BC = (0, - 10) - (2, - 9)

BC = (- 2, - 1)

AC = (0, - 10) - (- 3, 2)

AC = (3, - 12)

Second, calculate the magnitudes of the three sides:

AB = √[5² + (- 11)²]
AB = √146

BC = √[(- 2)² + (- 11)²]

BC = 5√5

AC = √[3² + (- 12)²]

AC = 3√17

Third, add the three lengths to find the perimeter:

p = √146 + 5√5 + 3√17

p ≈ 35.633

The statement reports a typing mistake that it would take a triangle for an angle, which is absurd since angles only have one vertex. Correct statement is shown below:

Find the perimeter of Δ ABC to the nearest hundred, given the coordinates of its vertices A(x, y) = (- 3, 2), B(x, y) = (2, - 9) and C(x, y) = (0, - 10).

The average rate of change over the entire slide if the height of the slide is 2 feet is; -3.9

Average rate of change is defined as a measure of how much the function changed per unit, on average, over that interval.

First, we will calculate the average rate from x = 0 to x = 15:

We have:

R = ((80 - 10)/(0 - 15))

R = -4.667

Let us now calculate average rate of change for the entire interval supposing that the height of the slide is 2 feet,:

From x = 0 to x = 20, we have;

R = ((80 - 2)/(0 - 20))

R = -3.9

He has a total of $60 to spend on hamburgers and tacos.

The inequalities that would be used to  represent the possible values for the number of hamburgers purchased, h, and the number of tacos purchased, t is as follows:

Therefore,

h = number of hamburgers purchased

t = the number of tacos purchased

D isn't the answer because even though [tex]\sqrt{5}[/tex] is irrational, you're adding [tex]\sqrt{5}[/tex] and then subtracting [tex]\sqrt{5}[/tex] from the total sum. Hence the total sum would be 5+14.

If Mei spent $66 buying fabric that costs $7.50 per yard, then she bought 8.8 yards of fabric

Given,

The total amount Mei spent = $66

Cost of fabric = $7.50 per yard

Substitute the values and divide it

How many yards of fabric Mei bought = [tex]\frac{66}{7.50}[/tex]

Step-by-step explanation:

"complimentary" means together they have 90°.

"supplementary" means together they have 180°.

which can be easily and quickly found on any internet search.

7.

A = 70°

A + B = 90°

70 + B = 90

B = 90 - 70 = 20°

B + C = 180°

20 + C = 180

C = 180 - 20 = 160°

8.

A + B = 90°

B + C = 180°

C = 100°

B + 100 = 180°

B = 180 - 100 = 80°

A + 80 = 90

A = 90 - 80 = 10°

The equation is 6.5 (r-1) + 5.5  = 259 or 6.5 r - 1 = 259.

In this case, r stands for the overall number of rows.

The answer indicates that each row is 6.5 cm tall.

A formula known as an equation uses the equals sign (=) to express how two expressions are equal. The word "equation" and its cognates in other languages may have slightly different meanings. For instance, in French, an equation is defined as having one or more variables, while in English, any well-formed formula consisting of two expressions related with an equals sign is an equation. The task of solving an equation with variables entails figuring out which values of the variables cause the equality to hold true. The unknown variables are also known as the variables for which the equation must be solved, and the unknown variable values that fulfill the equality are known as the equation's solutions. Identity equations and conditional equations are the two types of equations.

The height of the top row is 6.5 - 1 = 5.5 cm.

Except for this row, there are total rows of = (r-1)

So, 6.5 is the total length of these rows (r-1)

The overall length of the wall is therefore equal to the sum of the (r-1) row and the top row.

However, once more in line with the inquiry,

Exactly 259 centimeters must be on the wall.

⇒ 259 = 6.5(r-1) + 5.5

⇒ 6.5(r-1) + 5.5 = 259

⇒ 6.5 r - 6.5 + 5.5 = 259

⇒ 6.5 r - 1 = 259

Which is the required equation for finding the number of rows (r).
