The sum of angles of a triangle formed in a spherical geometry exists equivalent to 180∘.

A category of non-Euclidean geometry, spherical geometry is a subset of elliptical geometry. Any type of geometry that is not founded on conventional planes is known as non-Euclidean geometry. Lines in non-Euclidean geometry are not always the usual straight lines found in Euclidean geometry (i.e., plane geometry).

We require opposing sides and angles in order to use the sine rule. We can utilise this knowledge to locate the side that is opposite the other angle if we know two angles and one of the sides opposite. Accuracy points may be lost because of this.

Answer:  A. 0

This system of equations has no real solutions. The equation x² + y² = 36 represents a circle with center (0,0) and radius 6, while the equation 3x - y + 1 = 0 represents a line in a 2-dimensional plane. Since a line and a circle do not intersect at exactly one point in general, this system of equations have no common point, and therefore no real solutions.

Step-by-step explanation:

The concept given is a Probability, It is a branch of mathematics that deals with the occurrence of a random event. The answer is P(A|B)=P(B|A).

Probability is the branch of mathematics concerning numerical descriptions of how probable an event is to do, or how likely it's that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates the impossibility of the event and 1 indicates certainty.

Inverse probability is the probability of unobserved effects; or, more technically, the probability distribution of an unobserved variable. It's generally considered an obsolete term.

In probability proposition and statistics, an inverse distribution is the distribution of the complementary of an arbitrary variable. Inverse distributions arise in particular in the Bayesian environment of previous distributions and posterior distributions for scale parameters.

Answer:

  28°

Step-by-step explanation:

You want the smallest angle in a right triangle if the difference from the larger one is 34°.

This is one of a class of problems in which you want to find values that have a particular sum and a particular difference. They all have the same generic solution:

Here, the sum of the two acute angles in a right triangle is 90°. The problem statement tells you their difference is 34°. That means the smaller angle is ...

  smaller angle = (90° -34°)/2 = 56°/2 = 28°

The smallest angle is 28°.

__

Additional comment

The largest acute angle is (90° +34°)/2 = 124°/2 = 62°. You will notice this is the complement of the 28° angle found above, and differs by ...

  62° -28° = 34° . . . . as required by the problem statement

If you don't want to just jump to the answer, you can write an equation for the smallest angle (x). The larger will be (x+34).

  x +(x +34) = 90 . . . . . the two acute angles are complementary

  2x = 90 -34

  x = (90 -34)/2 = 56/2 = 28 . . . . . this should look familiar

Answer:

y = [tex]\frac{-A}{B}[/tex] x + [tex]\frac{C}{B}[/tex]

y = 6/5 x + 9/5

Step-by-step explanation:

Ax  + By = C  Subtract Ax from both sides

Ax - Ax + By = -AX + C

By = -AX + C  Divide both sides by B

y = [tex]\frac{-A}{B}[/tex] x + [tex]\frac{C}{B}[/tex]

-6x + 5y = 9   Add 6x to both sides

-6x + 6x + 5y = 6x + 9

5y = 6x + 9  Divide both sides by 5

y = 6/5 x + 9/5

The value of x for which the rational expression equals to zero is -4

An equation is said to be linear if the maximum power of the variable is consistently 1. Another name for it is a one-degree equation. A linear equation with one variable has the conventional form Ax + B = 0. In this case, the variables x and A are variables, whereas B is a constant. A linear equation with two variables has the standard form Ax + By = C. Here, the variables x and y, the coefficients A and B, and the constant C are all present.

A linear equation is one that has a degree of 1 as its maximum value. No variable in a linear equation, thus, has an exponent greater than 1. A linear equation's graph will always be a straight line.

A linear equation is an algebraic equation in which each term has an exponent of 1, and which, when plotted on a graph, always yields a straight line. It is called a "linear equation" for this reason.

The equation is

2 - x +x/2 + x = 0

⇒ x/2 = -2

⇒ x = -4

The regular price of each shoe pair is $36.75

To find the regular price of each pair of shoes before the discount, we need to use algebra. Let x be the regular price of each pair of shoes. We know that:

3x = regular price of 3 pairs of shoes

We also know that Gwen paid $110.25 after the discount, so we can set up the following equation:

3x - discount = 110.25

We don't know the discount, so we can't solve for x yet.

But we can use the fact that Gwen bought 3 pairs of identical shoes to find the discount.

discount = regular price of 3 pairs of shoes - price paid after discount

= 3x - 110.25

Now we can substitute this expression for the discount into the first equation:

3x - (3x - 110.25) = 110.25

Simplifying this equation gives:

110.25 = 110.25

So x = regular price of each pair of shoes = $110.25/3 =

The table that represents a linear equation is the first one, and the line can be:

y = -4x - 1

A general linear function can be written as:

y = a*x + b

Where a is the slope and b is the y-intercept.

Now, notice that if we evaluate the line in x + 1, we will get:

y = a*(x + 1) + b

y = a*x + a + b

So, for an increase of one unit on the variable x, we have a constant increase in the y value.

Now, if you look at the first table, you can see that for each increase of 1 unit on the value of x, the value of y decreases by 4.

So that is the table that can represent a linear function.

And the line is:

y = -4x - 1

A line passes through the points (5,9) and (4,6) is y=3x-6.

The slope intercept form of a straight line is one of the most common forms used to represent the equation of a line. The slope intercept formula can be used to find the equation of a line when given the slope of the straight line and the y-intercept.

The standard form of the slope intercept form is y=mx+c.

The given coordinate points are (5,9) and (4,6).

Here, slope m=(6-9)/(4-5) =3

Substitute m=3 and (x, y)=(5, 9) in y=mx+c, we get

9=3×5+c

9-15=c

c=-6

Answer: A quadratic function is a polynomial function of form f(x) = ax^2 + bx + c where a,b, and c are constants, and a is not equal to zero.

The given functions are:

(4a + 2)(2a - 1) + 1 = 0

2y + 2(3y - 5) = 0

2b(b - 7) + b = 0

The quadratic function(s) among them are:

2. (4a + 2)(2a - 1) + 1 = 0

2b(b - 7) + b = 0

The first one 8 - 5x = 4(3x - 1) is linear and not a quadratic function, and the third one 2y + 2(3y - 5) = 0 is also linear, not a quadratic function.

Note that to identify a quadratic function, we can look for the pattern of x^2 or y^2 in the equation.
