((x^2-3x-18)/(x+3))
((x-6)(x+3))/(x+3)

Determine the length of the legs in the right triangle below.
Marysya12 [62]

Answer:

x = 14

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

x² + x² = (14\sqrt{2} )²

2x² = 392 ( divide both sides by 2 )

x² = 196 ( take the square root of both sides )

x = \sqrt{196} = 14

Thus the congruent legs are 14 cm

What are the values the values of a and b?
Setler [38]
The segment marked 20 is the geometric mean of the two pieces into which it splits the hypotenuse. You get the proportion

\frac{20}{a} = \frac{21}{20}

Solving,

21a =(20)(20) \\ 21a = 400 \\ a = \frac{400}{21}

To find  b,  use the fact that  b  is the geometric mean of the whole hypotenuse, 21 + a, and the part that is attached to it,  a.

\frac{b}{a} = \frac{21+a}{b}

A little arithmetic shows that 21+a = \frac{841}{21}.

\frac{b}{\frac{400}{21}} = \frac{\frac{841}{21}}{b} \\ b^2 = \frac{336400}{441} \\ b=\frac{580}{21}
