Answer:

2.91 units

Step-by-step explanation:

If and only if this is a right triangle, we can apply the some fimctopm to determine the length of side BD:

                              side BC

tan 20 degrees = ---------------

                                    8

or side BC = 8 tan 20 degrees.  Since tan 20 degrees = 0.364 radians,

side BC has length 8(0.364) = 2.91 units

What is equation ?

In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal. For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.

Marla is four years less than twice as old as Darla can be represented as : 2y - x = 4

sum of their ages is 47 can be represented as : x + y = 47

Solving both the equation using addition we got ,

3y = 51

y = 17

Substituting the value of y in x + y =47 , we get

x + 17 = 47

x = 47 -17

x = 30

Hence , Marla is 30 years old.

what is number line?

A number line is a visual representation of real numbers used in introductory mathematics. It is an image of a magnitude line. On the number line, each point represents a real number, and each real number is taken to represent a point. Increments on a number line are separated by equal distances.

What is the length of JL, nearest tenth

Answers

Answer:

I believe the answer is 45.

Step-by-step explanation:

a 90 degree angle is represented by a square on the corner.

So half of 90 is:

90 ÷ 2 = 45

the angle next to the letter M is 90 degreess, so the other side of the line is also 90 degrees.

45 + 90 = 135

and 180 - 135 = 45

(You subtract 135 from 180 since " the sum of angles of a triangle equals the straight angle", which is 180 degrees.

So, the length of JL is equal to 45 degrees.

A triangle has sides of 7, 24, and 25 cm. The length of the hypotenuse is equal to 25 cm if the triangle is a right triangle.

What are the angles of a 7/ 24/ 25 triangle?

The triangle's sides are 7 cm, 24 cm, and 25 cm, as is obvious.

49, 576, and 625 are the results of squaring the lengths of the side of the.

49 + 576 = 625\s(7)2 + (24)2 = (25)2

As a result, the aforementioned equation satisfies Pythagoras's theorem. As a result, it is a right-angled triangle.

the hypotenuse is 25 cm long.

Angles of 16.26 degrees and 73.74 degrees are suitable.

Yes, since 72+242=252 (sum of squares on smaller two sides equals square on largest side).

what is polynomial ?

The location on the y-axis where the slope of the line passes is known as the intersection point in mathematics. a point on a line or curve where the y-axis crosses. The equation for the straight line is given as Y = mx+c, where m denotes the slope and c the y-intercept. In the intercept form of the equation, the line's slope (m) and y-intercept (b) are highlighted. The slope and y-intercept of an equation with the intercept form (y=mx+b) are m and b, respectively. There are several equations that can be rewritten to look like slope intercepts. The slope and y-intercept are both modified to 1 if y=x is rewritten as y=1x+0, for example.

given

(4 - a) * ( a3 + 7a - 18 )

= 4a3 + 28a - 72 - a4 + 7a2 + 18 a

= a3 + 3a2 + 46a + 72

x^2 - 19x +c

Answers

Answer:

Step-by-step explanation:

We need to transform the given x^2 - 19x + c into the form

                                                      (x - a)^2 + d

by completing the square:

1.  Take half of the coefficient (-19) of x, obtaining -19/2.

2.  Square this result, obtaining 361/4.

3.  Add this to x^2 - 19x, and then immediately subtract it:

    x^2 - 19x + c becomes x^2 - 19x + 361/4 - 361/4+ c

4.  Replace the first three terms with (x - 19/2)^2:

     x^2 - 19x + 361/4 - 361/4+ c  =>  (x - 19/2)^2 - 361/4 + c

5.  Put this into final form: (x - 19/2)^2 - (361/4 - c)

The prime factor trees for 24 and 84 are attached in the image below. The Lowest Common Multiple of 24 and 84 is 168.

What are prime factors?

A natural number other than 1 whose only factors are 1 and itself is said to be a prime factor. In actuality, the first few prime numbers are 2, 3, 5, 7, 11, and so forth. The lowest of two or more natural numbers' common multiples is referred to as the Lowest Common Multiple (LCM). A prime factor is a natural integer, other than 1, whose sole factors are itself and 1. Actually, 2, 3, 5, 7, 11, and so forth are the first few prime numbers. The term "Lowest Common Multiple" refers to the common multiple of two or more natural integers that is the lowest (LCM).

The prime factors of 24 are: 2,2,2 and 3.

The prime factors of 84 are: 2,2,3 and 7.

Now, The Lowest Common Multiple (LCM) of 24 and 84 is calculated using the prime factors of both the numbers.

LCM= 2*2*2*3*7= 168

Hence, The Lowest Common Multiple of 24 and 84 is 168.
