The distance, In feet, from the base of the ladder to the base of the wall is 4.2 ft.

He needs to move the ladder 0.1 ft closer to the base of the building.

The situation forms a right angle triangle.

Right angle triangle has one of its angles as 90 degrees. The sides and angle can be found using trigonometric ratios.

The length of the ladder is the hypotenuse of the triangle formed. Therefore, the distance, In feet, from the base of the ladder to the base of the wall can be calculated as follows;

cos 65° = adjacent / hypotenuse

cos 65° = d / 10

d = 10 × 0.42261826174

d = 4.22618261741

d = 4.2 ft

She needs to move the ladder so it reached a window 9.6 feet above the ground. Therefore, the distance from the base of the ladder and the wall is as follows;

cos 65 = d / 9.6

d = 9.6 × 0.42261826174

d = 4.05696

d = 4.1

Therefore, he needs to move the ladder 0.1 ft closer to the building.

The required unit multipliers that should be used to change feet to inches is: 12 in/1 ft

Unit multipliers are used to convert one unit of measurement to another by the multiplication of the measure we're converting by a unit multiplier that cancels out the other units, retaining only the preferred choice or desired answer.

From the given information:

However, it is important to note that when using unit multipliers, the name of the measure in the numerator should be the same as the name of the unit in the desired answer.

The term used to multiply by when converting measures should always be less than the given measure.

The cord of wood can be determined by multiplying the length, depth and height of the wood together, then dividing the answer but 128.

Answer: x = 5

Step-by-step explanation:

    If you need to solve for x,

Given:

-1 (1 + 7x) - 6(-7 -x) = 36

Distribute:

-1 - 7x + 42 + 6x = 36

Combine like terms:

- x + 41 = 36

Subtract 41 from both sides of the equation:

- x = -5

Divide both sides by -1:

x = 5

Answer: 75

Step-by-step explanation:

The measure of the red arc or chord is  75 degrees

A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.

From the given figure we observe that ∠ACB is vertical angle of ∠ECD

∠ECD = 75 degrees

∠ECD = ∠ACB as they are vertical angles

∠ACB = 75 degrees

∠ACB  is the central angle.

The central angle of an arc is the central angle subtended by the arc. The measure of an arc is the measure of its central angle.

So measure of arc AB is 75 degrees

Hence,  the measure of the red arc or chord is  75 degrees

Using Binomial series formula:

Step-by-step explanation:

we have to solve 2 right-angled triangles via Pythagoras

c² = a² + b²

with c being the Hypotenuse (the side opposite of the 90° angle).

one triangle is 37, 12 and the longer part of the long diagonal.

the second triangle is 13, 12 and the shorter part of the long diagonal.

the whole diagonal is then the sum of both parts.

37² = 12² + longer part²

1369 = 144 + longer part²

longer part² = 1225

longer part = 35

13² = 12² + short part²

169 = 144 + short part²

25 = short part²

short part = 5

so, the total diagonal is 35 + 5 = 40 units.

The length of the longer diagonal obtained using Pythagorean theorem is 40 units

The Pythagorean theorem is a fundamental geometric relationship that states that the square of the hypotenuse side of a right triangle is equivalent to the sum of the squares of the other two sides (the legs). Mathematically, we get

c² = a² + b²

Where a and b are the lengths of the legs  and c is the length of the hypotenuse side of the right triangle.

The diagonals of a kite are perpendicular to each other

The diagonal that is bisected in a kite is the shorter diagonal

The lengths from the left point to the middle and the distance from the right point to the middle are both 12, which indicates that the diagonal from left to right of the kite is bisected, which is the shorter diagonal. Therefore;

The length of the shorter diagonal is; 12 + 12 = 24

Therefore, the longer diagonal forms two right triangles to the left and two right triangles to the right

The hypotenuse length of the right triangles are 37 and 13, while the leg common to both right triangles on each side is half the length of the shorter diagonal, or 12

The Pythagorean theorem indicates that we get;

Length of the longer diagonal = √(13² - 12²) + √(37² - 12²) = 40

The length of the longer diagonal is 40 units

Apply the distributive law [tex]a(b + c) = ab + ac[/tex] :

[tex]\implies 9x + 18 + 3x = 1[/tex]

Collect and combine like terms:

[tex]\implies 9x + 3x+ 18 = 1[/tex]

[tex]\implies 12x + 18 = 1[/tex]

Subtract 18 from both sides:

[tex]\implies 12x + 18 - 18 = 1 - 18[/tex]

[tex]\implies 12x = -17[/tex]

Divide both sides by 12:

[tex]\implies \dfrac{12x}{12}=-\dfrac{17}{12}[/tex]
