The hypotenuse of a right triangle is 10cm long. One of the triangle's legs is three times the length of the other leg. Find the

vivado [14]

Answer:

The lengths of the three sides are 10 cm, 9.49 cm and 3.16 cm

Step-by-step explanation:

Let

c ------> the length of the hypotenuse of a right triangle

x -----> the length of one leg

y -----> the length of the other leg

we know that

$c^{2}=x^{2}+y^{2}$ -----> equation A (Pythagoras Theorem)

$c=10\ cm$ ----> equation B

$x=3y$ -----> equation C

Substitute equation B and equation C in equation A and solve for y

$10^{2}=(3y)^{2}+y^{2}$

$100=10y^{2}$

$y^{2}=10$

$y=\sqrt{10}\ cm$

$y=3.16\ cm$

Find the value of x

$x=3(\sqrt{10})=9.49\ cm$

therefore

The lengths of the three sides are 10 cm, 9.49 cm and 3.16 cm
