Question

In the picture shown below, what proportion would NOT give the correct value of x?

Answer 1

Answer: (c)

Step-by-step explanation:

In the given figure, two triangles are similar namely $\triangle ABC$ and $\triangle ADB$

For similar triangles, the ratio of the corresponding sides are equal.

For option (a), Hypotenuse to Perpendicular ratio is given, that is correct

Similarly for option (b), Perpendicular to hypotenuse ratio is given

Both option (a) and (b) gives the same value of $x$ that is,

$\Rightarrow x=\sqrt{81\times 45}\\\Rightarrow x=60.37$

Option (c) does not give the correct value of  $x$

Answer 2
