Answer: It is equal to the measure of angle C.

Step-by-step explanation:

If we know that Triangle ABC isosceles, then that means two sides and two angles are congruent to each other. Angle A must the topmost angle, and Angle B and C are probably the base angles. So, saying that, the base angles and sides are congruent to each other. Hence, Angle B must be equal to Angle C.

Areas of mathematics, and give a precise definition of each.

Sol: importance: mathematics can be tricky, so precise definitions are essential. Without them, there can be confusion, which will generate the wrong answer more often than not.  It teaches the students exactly how to use formulas and under what condition a mathematical statement is true.

Some words related to geometry that are quite hard to define precisely are the line, the plane, and the point. In mathematics, the unit square is area one and any other shape.

Answer:

Step-by-step explanation:

Standard form of the equation of a circle with center (h, k) and radius r:

[tex] (x - h)^2 + (y - k)^2 = r^2 [/tex]

Compare it to the given equation, and you get:

Answer:

- 21

Step-by-step explanation:

The minimum value occurs at the vertex of the function

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

To obtain this form use the method of completing the square

Given

f(x) = x² - 6x - 12

add/ subtract ( half the coefficient of the x- term)² to x² - 6x

f(x) = x² + 2(- 3)x + 9 - 9 - 12

     = (x - 3)² - 21

with vertex = (3, - 21 )

The minimum is the value of k, that is minimum value = - 21

Answer:

67 inches

Step-by-step explanation:

Since the question is asking how many inches total do you have, we need to add up the 2 values given:

39 inches + 28 inches = 67 inches.

We can convert this to feet by dividing by 12:

67 in /12 in/ft ≈ a little over 5 and a half feet

The total numbers of sections are 16.

Step-by-step explanation:

Given:

Number of boys in school = 576

Number of girls in school = 448

To find: Total Number of sections such that each section has either boys or girls.

Height Common Factor ( HCF ) of both number gives the number of students in a section.

HCF of 576 and 448

576 = 2 × 2 × 2 × 2 × 2 × 2 × 3 × 3

448 = 2 × 2 × 2 × 2 × 2 × 2 × 7

HCF = 2 × 2 × 2 × 2 × 2 × 2 = 64

Number of sections of Boys = 576/64 = 9

Number of sections of girls 448/64 = 7

Total Number of sections = 9 + 7 = 16

Therefore, The total numbers of sections are 16.

Answer:

0.25 miles per minute, travels 5 miles in 20 minutes

Step-by-step explanation:

First, we have to find out how many miles he can travel in a minute.

We know that he travels 15 miles every hour, and we know that one hour is 60 minutes.

So, we can divide 15 miles by 60 minutes in order to get his pace for miles per minute

Then we can just multiply 0.25 miles by 20 minutes

which gives us 5 miles in 20 minutes

An equation is formed of two equal expressions. The value of x in the given equation is equal to 6.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

The given equation can be solved for x as shown below.

7x = 42

Divide both the sides of the equation by 7,

7x / 7 = 42/ 7

Simplifying both sides of the equation,

x = 6

Hence, the value of x in the given equation is equal to 6.

Answer:

26

Step-by-step explanation:

If FG is 19 and GH is 7 and you are trying to find the combined length of FG and GH then add 19 and 7.

The sum of line segment FG and GH will result FH as 26.

A line section that can connect two places is referred to as a segment.

In other words, a line segment is just part of a big line that is straight and going unlimited in both directions.

Given the line FH with two segment FG and GH

So,

FH = FG + GH

FH = 19 + 7

FH = (20 - 1) + 7

FH = 20 + 7 - 1

FH = 27 - 1 = 26

Hence "The sum of line segment FG and GH will result in FH as 26".

Answer:

Attachment 1 :-   x = 3/2

Attachment 2 :-  m + r = 154°

Step-by-step explanation:

Attachment 1 :-

[tex]9^(^2^-^x^) = 3\\=> 3^2^(^2^-^x^) = 3\\[/tex]

As the base 3 is same on both the sides , cancel the base 3 from both left & right side of eqn. After that we will get:-

[tex]2(2 - x) = 1\\=> 2 - x =\frac{1}{2} \\=> x = 2 - \frac{1}{2} = \frac{3}{2}[/tex]

Attachment 2 :-

PQR is a straight line . It's given that m + n = 110°

But we know that m + n + r = 180° ..............eqn.1

So substituting the value of m+n in eqn.1 gives :-

m+n+r = 180°

=> r + 110° = 180°

=> r = 180° - 110°

       = 70°

It's also given that n+r = 96°

So putting the value of r in the above gives ,

n+r = 96°

=> n + 70° =96°

=> n = 96° - 70°

        = 26°

Putting the value of n in eqn.1 gives

m + n = 110°

=> m + 26° = 110°

=> m = 110° - 26°

        = 84°

So m + r = 84° + 70° = 154°
