Question

In the formed right-angle triangle what is the length of the hypotenuse?

1. 15 m

2. 20 m

3. 25 m

4. 30m



Please answer this question.​

Answer 1

Answer:

hypotenuse length= 25 cm

Step-by-step explanation:

by pythagoras theorem:

hypotenuse²= base²+ perpendicular ²

H²= 15²+20²

Answer 2

Answer:

option(3) is correct answer , which is 25 m.

Step-by-step explanation:

Explanation:

Given,

Height of unbroken part of tree is 15 m

and broken part of the tree has fallen at 20m away from the base of the tree .

Let height of unbroken part of tree be AB and

let AC is the distance between the base and the broken part of the tree which is 20m

Step 1:

In right angle triangle ACB.

By pythagoras theorem we have

$BC^{2} = AB^{2} +AC^{2}$

put the value of AB and AC

∴ $BC^{2} = (15)^{2} +(20)^{2}$

⇒ $BC = \sqrt{225+400}$

        = $\sqrt{625}$ = 25m

Final answer :

Hence , the length of hypotenuse is 25m, which is option (3)
