Setler [38]

Answer:

x = - 12

Step-by-step explanation:

∠ FCD + ∠ BCF = ∠ BCD , substitute values

x + 41 + x + 78 = 95 , that is

2x + 119 = 95 ( subtract 119 from both sides )

2x = - 24 ( divide both sides by 2 )

x = - 12

The width of a rectangle is 4 feet and the diagonal length of he rectangle is 13 feet what is the measurement is the closest to

AURORKA [14]

Answer:

The length is APPROXIMATELY equal to 12.4.

Step-by-step explanation:

Use the converse of the Pythagorean Theorem ( $a^{2}$ + $b^{2}$ = $c^{2}$ [where "c" is both the longest side and the hypotenuse]) since a rectangle's diagonals will always cut it into two right triangles:

$13^{2} = 169$

$4^{2} =16$

169-16=153.

$\sqrt{153}$ ≈ 12

$\sqrt{153}=12.36931688$

or if the problem has to be exact (using radicals)

3* $\sqrt{17}$

I hope this helps ;)
