Find the value of x
iVinArrow [24]

Answer:

x = 121

Step-by-step explanation:

Let the measure of the altitude of the given triangle be h units.

By geometric mean theorem:

h =  \sqrt{23 \times x}  \\  \\ h =  \sqrt{23x}  \\  \\ now \: by \: pythagors \: theorem \\  \\  {(x + 11)}^{2}  =  {h}^{2}  +  {x}^{2}  \\  \\   \cancel{{x}^{2}}  + 22x + 121 =  {( \sqrt{23x} )}^{2}  +  \cancel{{x}^{2}} \\  \\ 22x + 121 = 23x \\  \\ 22x - 23x =  - 121 \\  \\  - x =  - 121 \\  \\ x = 121
