Step-by-step explanation:
Here we have , A student is asked to find the length of the hypotenuse of a right triangle. The length of one leg is 32 centimeters, and the length of the other leg is 25 centimeters. The student incorrectly says that the length of the hypotenuse is 7.5 centimeters. We need to find:
A)
We have , One length as 32 cm and other as 25 cm , as
By Pythagoras Theorem ,
⇒![Hypotenuse^2 = Perpendicular^2+Base^2](/tpl/images/0560/7338/9a298.png)
⇒![Hypotenuse^2 =32^2+22^2](/tpl/images/0560/7338/1dc39.png)
⇒![\sqrt{Hypotenuse^2} =\sqrt{1024+484}](/tpl/images/0560/7338/e6917.png)
⇒![Hypotenuse =39cm](/tpl/images/0560/7338/e8e62.png)
So ,
of right angle triangle! .

Explanation
This is because in similar triangles, the sides are ratios/multiples of each other.
E.g.
Small Triangle
Hypotenuse = 5
Adjacent = 3
Opposite = 4
Big Triangle
Hypotenuse = 10
Adjacent = 6
Opposite = 8
All sides in big triangle are twice that of the small triangle.
Consider ratio of hypotenuse and adjacent
5/10 = 3/6
This is the same value.
The other statements can be elements of triangles without them needing to be similar
