Rule y = x - 3 plz help me :(

Andru [333]

<h3>The answer!</h3>

<h3>Lets do the Solve the equetion first!</h3>

<h3>Solution:</h3><h3> $y = x - 3 \\ = y - x = - 3 \\ = - x = - 3 - y \\ = - x = - y - 3 \\ = x = y + 3$ </h3><h3>The answer is </h3><h3> $x = y + 3$ </h3><h3>꧁✰_______❀Edilyn❀_______✰꧂</h3><h3 />

A guy wire to a tower makes a 72 degrees angle with level ground. At a point 30 ft farther from the tower than the wire but on t

Andreyy89

So.. checking the picture below

we can say y = y, or just do a substitution and end up with

$\bf tan(72^o)=tan(30^o)(30+x)\implies 3.08x=\cfrac{30}{\sqrt{3}}+\cfrac{1}{\sqrt{3}}x
\\\\\\
3.08x-\cfrac{1}{\sqrt{3}}x=\cfrac{30}{\sqrt{3}}\implies 2.5x\approx 17.32\implies x\approx \cfrac{17.32}{2.5}$

once you know, how long is "x", then you can simply use the cosine of 72° to get "r"

thus $\bf cos(\theta)=\cfrac{adjacent}{hypotenuse}\qquad cos(72^o)=\cfrac{x}{r}\implies r=\cfrac{x}{cos(72^o)}$

The area of the rectangle which is 28 square units is divided into two parts one is 4 square units and other one is 7 square units.

<h3>What is the area of the rectangle?</h3>

It is defined as the area occupied by the rectangle in two-dimensional planner geometry.

The area of a rectangle can be calculated using the following formula:

Rectangle area = length x width

It is defined as two-dimensional geometry in which the angle between the adjacent sides is 90 degrees. It is a type of quadrilateral.

The area of the larger rectangle = 28 square units

The area of the smaller rectangle = 4 square units

Let suppose the x be the area of the large rectangle

4x = 28

x = 7 square units

Thus, the area of the rectangle which is 28 square units is divided into two parts one is 4 square units and other one is 7 square units.
