Question

One leg of a right triangle is 3 feet and the hypotenuse is 7 feet long. Find the length of the other leg

Answer 1

Answer:

Step-by-step explanation:

7^2-3^2=49-9.

=40

=2√10

Answer 2

let other leg of right angle triangle be 'x'

one leg = 3 feet ,

hypotenuse = 7 feet

other leg = √[(hypotenuse)^2 - (one leg)^2]

x = √(7)^2 - (3)^2

x = √40 = 2√10feet

Answer:

other leg of right angle triangle= 2√10 feet
