I have absolutely no idea what I am doing so yeah pls help me lol.

Answer:

x= [tex]5\sqrt{5}[/tex]

Step-by-step explanation:

To solve this problem we first observe the Pythagoras equation. If a= 10 and b =5 are the lengths of the legs of a right triangle and c= x is the length of the hypotenuse, then the sum of the squares of the lengths of the legs is equal to the square of the length of the hypotenuse.

This relationship is represented by the formula:

[tex]a^{2} + b^{2} = c^{2}[/tex] =>[tex]10^2 +5 ^2 = x^2[/tex]

=> 100 + 25 = [tex]x^2[/tex]

=> [tex]\sqrt{125}[/tex] = x => [tex]\sqrt{25} \sqrt{5}[/tex] = x

=> x= 5[tex]\sqrt{5}[/tex]

Answer:

It is not a right triangles because 15^2 + 13^2 is NOT EQUAL to 19^2

let x, y, and z be the angles inside the triangle.

Law of cosines says:

19^2 = 13^2 + 15^2 - 2(13)(15)cos x

361 = 169 + 225 - 390 cos x

-33 = -390 cos x

-33/-390 = cos x

11/130 = cos x

x = inverse cosine (11/130)

= 85.14609471338569.....

Per law of sines:

sin x/19 = sin y / 13

(13/19)sinx = sin y

inverse_sine ( (13/19) sin x) = y

y = 42.9810733896016548....

Per law of sines

sin x/19 = sin z / 15

z = inverse_sine( (15/19) sin x)

= 51.8728352950227805....

So it is an acute triangle and yes, these angles add up to 180

Answer:

  ?° = 153°

Step-by-step explanation:

The measure of an arc is the same as the measure of the central angle it subtends. The arc is marked 153°. The central angle (?°) has that same measure.

  ?° = 153°

Step-by-step explanation:

Try first to solve the equation by factoring. Be sure that your equation is in standard form before you start your factoring attempt.

Answer:

$45.90

Step-by-step explanation:

Multiply without the decimal points, then put the decimal point in the answer: 85 x 54 = 4590

8.5 has 1 decimal place

5.4 has 1 decimal place

Therefore, the answer has 2 decimal places

= 45.90

Refine: 45.9

Answer:

C

Step-by-step explanation:

First find the equation of the circle

the general formula for a circle (x-h)² + (y-k)² = r² where (h=0, k=0) are the coordinates of the center and r is the radius that we do not know

the distance between the center (0, 0) and the point (3,5) is the radius

distance formula d² = (x2-x1)² +(y2-y1)²  where (x1=0,y1=0) and (x2=3, y2=5)

d² = (3-0)² + (5-0)² = 3² +5² = 9+ 25 = 34 =r²

(x-0)² + (y-0)² = 34 ; x²+y² =34 is the equation of the circle

Second check if any of the points are on the circle by substituting x and y with de given coordinates.

A. for (-2, 6) we have (-2)²+6² =34 so 4+36 =34 false

B. for (6, -√5) we have 6²+(-√5)² =34 so 36+5=34 false

C. for (1, √33) we have 1²+(√33)² =34 so 1+33 =34 true

D. for (-2√2, 4) we have (-2√2)²+4² =34 so 8+16=34 false

1 gallon is 4 quarts so you would do 11x4=44 and .05x4=2

44+2=46

Answer:

y= -1/4x+2

Step-by-step explanation:

y=mx+b is the slope intercept form.

We first must isolate y by adding 1/2x on both sides.

-2y=-4+1/2x

next we multiple by -1/2 to get rid of the -2

y=2-1/4x

y=-1/4x+2

The  difference between two positive numbers is 7 and the difference between these  cubes is 805. If 'A' represents their product and 'B' represents the sum of their squares,

So,

Let the number be n and m

A = n × m = nm

B = n² + m² = (n + m)²

Now

n³ - m³ = 805

(n - m) (n² + m² + nm) = 805

Since difference is 7

7 × n² + m² + nm = 805

n² + m² + nm = 805/7

n² + m² + nm = 115

(n² + n) + (m² + m) = 115

A + B = 115

Now

On squaring the first eq.

(n - m)² = (7)²

(n - m)² = 49

B - 2A = 49

Now

A + B - B + 2A = 115 - 49

A + 2A = 66

3A = 66

A = 66/3

A = 22

By using 2

B - 2(22) = 49

B - 44 = 49

B = 49 + 44

B = 93

A - B = 22 - 93 = -71

Answer:

Let's just find the value of the unknown degree next to 35 degrees.

180 - 35 = 145 degrees

Since 145 degrees is the unknown degree next to 35 degrees, it is vertical to the x it will be the same therefore your answer is 145 degrees.

Answer:

96

Step-by-step explanation:

To get 5 digit numbers using the digits 0,1,2,3,4 exactly once = 4*4*3*2*1 = 96.

Step 1:

1st digit can be 1, 2,3,4 ( it can't be 0) so there are 4 choices.

Step 2:

2nd digit = 4 choices.

Step 3:

3rd digit = 3 choices

Step 4:

4th digit = 2 choices

Step 5:

5th digit = 1 choice .

So the number of different 5 digit number is 4*4*3*2*1 = 96

Step-by-step explanation:

i am not much sure of that.

Answer:

Triangle :

Step-by-step explanation:

        The altitude of triangles,

Three altitudes :

Every triangle has three bases (any of its sides) and three altitudes (heights). Every altitude is the perpendicular segment from a vertex to its opposite side (or the extension of the opposite side).

         The heights. of triangle,

The three heights of a triangle :

Triangles each have three heights, each related to a separate base. Regardless of having up to three different heights, one triangle will always have only one measure of area. In some triangles, like right triangles, isosceles and equilateral triangles,

Answer:

Isosceles Triangle

Step-by-step explanation:

Two of the sides are the same, meaning by definition it is an isosceles triangle.

Answer: yes 3/4 is greater

converting both fractions to decimals. The decimal 0.75 is bigger than 0.5, so 3/4 is bigger than 1/2.

Answer:

3/4 is greater than 1/2.

Step-by-step explanation:

One way to compare fractions is by making them have the same denominator.

You can do this by finding the least common denominator (LCM).

First, list the multiples of each denominator.

4: 4, 8, 12, 16, 20

2: 2, 4, 6, 8, 10

As you can see, 4 is the LCM.

Now, change the fractions to where they denominators of 4.

**WHICHEVER NUMBER YOU MULTIPLY THE DENOMINATOR BY, YOU MUST ALSO MULTIPLY IT BY THE NUMERATOR.**

[tex]3/4*1/1=3/4[/tex] (STAYS THE SAME)

[tex]1/2*2/2=2/4[/tex]

Now, as you can see, 3/4 is larger than 2/4.

Therefore, 3/4 is larger than 1/2.
