Question

which of the following can be the sides of a right- "angle" triangle? ​

Answer 1

Answer:

b.

$\sqrt{2.4 \times 2.4 + 3.2 \times 3.2}$

=

$\sqrt{5.76 + 10.24}$

=

$\sqrt{16}$

=4

this sides can't of a right angle triangle

c.

$\sqrt{1.6 \times 1.6 + 3.0 + 3.0}$

=

$\sqrt{2.56 + 9.0}$

=

$\sqrt{11.56}$

=3.4

this sides can a right angle triangle.

Answer 2

Answer:

The Correct Answer is Option (d)

Step-by-step explanation:

In the beginning, You have to know...

For every Right Angled Triangle, it's true that,

             $a^{2} +b^{2} =c^{2}$

And here, $c$ must be the max value.

So, we have to make the values true for the upper condition.

Well,

In the Option (b),

$c$ = 7.9 cm

$a$ = 2.4 cm

$b$ = 3.2 cm

Here,

 $\sqrt{2.4^{2} + 3.2^{2} } = 4$ ≠ $c$

That's why These values of Option (b) cannot make a Right Angled Triangle.

In the Option (d),

$c$ = 3.4 cm

$a$ = 3.0 cm

$b$ = 1.6 cm

Here,

 $\sqrt{1.6^{2}+ 3.0^{2} } = 3.4=c$

That's why These values of Option (d) can make a Right Angled Triangle.

So, The Correct Answer is Option (d).

Hope you have understood the process...
