We can say that side lengths 6, 8 and 10 will make a right triangle. To make this statement, we use ___________ ____________ and

lina2011 [118]

To Prove :

Side lengths 6, 8 and 10 will make a right triangle.

Solution :

We know, by Pythagoras theorem :

$a^2+b^2 = c^2$

Here, c is the biggest side and a and b are other sides.

Putting given values in above equation.

$6^2+8^2 = 10^2\\\\36 + 64 = 100\\\\100 = 100$

Since, LHS = RHS .

Therefore, lengths 6, 8 and 10 will make a right triangle.

x + y = 24 where x and y are the 2 parts of diagonal Other diagonal wil be smaller that 24.
x^2 + z^2 = 13^2
y^2 + z^2 = 20^2 where z = 0.5 * length of smaller diagonal)

form last 2 equations

y^2 - x^2 = 20^2 - 13^2 = 231
now y = 24-x so we have

(24 - x)^2 - x^2 = 231

576 - 48x = 231

48x = 345

x = 7.1875

z^2 = 13^2 - 7.1875^2 = 117.34
z = 1.83

so smaller diagonal = 21.66 cm

looks like its the third choice.
