Both problems can be solved similarly since both shapes are Quadrilateral hence the sum of thier interior angels is 360
5.)
(x)+(x)+(4x-26)+(2x+18)=360
8x-8=360
x-1=45
x=46
6.)
(2x)+(x)+(x+10)+(2x-16)=360
6x-6=360
x-1=60
x=61

100 Points! Question Urgent!!!!!!

Ann [662]

Answer:

9

Step-by-step explanation:

<u>→You can use the Pythagorean Theorem to solve this, by plugging in the numbers, like so:</u>

<u /> $a^2+b^2=c^2\\x^2+(x-3)^2=(x+3)^2$

$x^2+x^2-6x+9=x^2+6x+9$

<u>→Subtract </u> $x^2-6x+9$ <u> from both sides:</u>

$x^2 = 12x$

<u>→Subtract 12x from both sides:</u>

<u /> $x^2 -12x=0$

<u>→Factor out x:</u>

<u /> $x(x-12)=0$

<u>→Separate, set = to 0, and solve:</u>

<u /> $x = 0\\x -12=0$ → <u>Add 12 to both sides:</u> $x = 12$

→So we have 0 and 12, as our answers. However, we cannot have 0 as a side length, since this would not be possible.

→All we need to do is take 12, and plug it into the equation for the shortest leg.

$x - 3=?\\12-3=9$
