What is the value of x in the triangle?
yulyashka [42]
<h3>Answer: C) x = 13</h3>

====================================================

Work Shown:

We have a right triangle with legs a = 5 and b = 12. The hypotenuse is c = x which is unknown for now.

Use the pythagorean theorem to find x.

a^2 + b^2 = c^2

5^2 + 12^2 = x^2

25 + 144 = x^2

169 = x^2

x^2 = 169

x = sqrt(169)  .... apply the square root to both sides

x = 13

Well...   the segment FG = 4x + 3, the segment GH = 7x - 12, now, the
 
segment FH = FG + GH, those two fellows added up, and we know that FG and GH are both equal halves because G is the midpoint.

thus, FG = GH
or

\bf 4x+3=7x-12\implies 3+12=7x-4x\implies 15=3x&#10;\\\\\\&#10;\cfrac{15}{3}=x\implies \boxed{5=x}\\\\&#10;-------------------------------\\\\&#10;thus\qquad &#10;\begin{cases}&#10;\overline{FG}=4x+3\\&#10;4(5)+3\\&#10;23\\&#10;------\\&#10;\overline{GH}=7x-12\\&#10;7(5)-12\\&#10;23&#10;\end{cases}\impliedby equal\ halves&#10;\\\\\\&#10;\overline{FH}=23+23\implies \overline{FH}=46\implies 6y-2=46&#10;\\\\\\&#10;6y=46+2\implies y=\cfrac{48}{6}

and fairly sure, you know how much that is.
