What is the length of the unknown leg in the right triangle? A right triangle has a side with length 20 meters, hypotenuse with length 25 meters, and side labeled b. StartRoot 5 EndRoot m 5 m StartRoot 45 EndRoot m 15 m

The length of the unknown leg of the triangle is 15 m.

Step-by-step explanation:

Length of one leg = 20 m

Length of the hypotenuse= 25m

As it is a right angled triangle we can use pythogoras theorem.

Let the unknown length be y

(20) (20)  + y(y) = (25) (25)

400 + y(y) = 625

y(y) = 225

y = √225

y = 15

The length of the unknown leg is 15 m.

the answer is c

hope this !
