Question

The hypotenuse of a right triangle is 65 m long. If one of the legs is 39 m long, how long is the other leg?​

Answer 1

Answer:

52 m

Step-by-step explanation:

(a^2) + (b^2) = (c^2)

(39^2) + (b^2) = (65^2)

(39^2) + (b^2) = (65^2)

1521 + (b^2) = 4225

(b^2) = 2704

b = 52

Answer 2

Answer:

use Pythagoras   theorem  to solve this

$C^{2}$= $A^{2}$+$B^{2}$

C is always the hypotenuse of a triangle  

Step-by-step explanation:

$65^{2}$ = $39^{2}$ +$B^{2}$

my calculator tells me that..

4225 =1521 +$B^{2}$

2704 = $B^{2}$

$\sqrt{2704}$ = B

52=B  

nice .. it worked out to a nice whole number
