<span>8 - 1/3x = 16
</span>⇒ -1/3x= 16-8
⇒ -1/3x= 8
⇒ x= -24
The final answer is -24~
Hello,
Assume x the smallest side.
y the third side
z the largest side
z=2x-4
y=10+x
x+y+z=86
==>x+(10+x)+(2x-4)=86
==>4x=86-10+4
==>x=20, y=30 and z=36
3: independent
4: dependent
First we have to find length of 1 side of the square. We can use formula for area of the square. A=a*a ==>

where a is length of the side.
From this formula we can find

a=

Now we just have to multiply it by 4, because there are 4 sides.
81*4=324 - its the answer
The largest angle of the pentagon with the given ratio of angles is: 180°.
<h3>What is a Pentagon?</h3>
A pentagon is a 5-sided polygon with 5 interior angles that have a sum of 540 degrees.
If the ratio of the angles are: 1:2:2:3:4, then the largest angle would be calculated as shown below:
4/(1+2+2+3+4) × 540
4/12 × 540 = 180°
The largest angle is: 180°.
