Answer:

Step-by-step explanation:

Here is an example:

$3x^{2} +7=55$

-7 on both sides of the equation

$3x^{2} =48$

divide by 3 on both sides

$x^{2} =16$

square root the $x^{2}$ and 16

x=±4

w=37

2w+w+69= 180 knowing that all triangles add up to 180 form an equation

3w+69=180 combine like terms and subtract 69 from both sides

3w=111 divide by 3 from both sides

w=37

Find the sides of a triangle if two of its sides are equal, the third side is 1 1 3 cm longer than the others, and its perimeter

Helga [31]

Answer: $137\dfrac{1}{3}\ cm,\ 137\dfrac{1}{3}\ cm,\ 250\dfrac{1}{3}\ cm$

Step-by-step explanation:

Let x be the equal sides of the triangle .

The , the third side would be x+113 cm.

The perimeter is the sum of all sides of a triangle.

So , The perimeter of triangle would be x+x+(x+113)= 3x+113 --------(1)

Since , it is given that the perimeter of triangle is 525. -----(2)

So from (1) and (2) , we have

$3x+113=525\\\\ 3x=525-113=412\\\\ x=\dfrac{412}{3}=137\dfrac{1}{3}$

Then, third side = $137\dfrac{1}{3}+113=250\dfrac{1}{3}\ cm$

Hence , the sides of a triangle are: $137\dfrac{1}{3}\ cm,\ 137\dfrac{1}{3}\ cm,\ 250\dfrac{1}{3}\ cm$
