In a right triangle the lengths of the legs are a and b. Find the length of the hypotenuse, if: a=3/7, b=4/7

Answer:
5/7.
Step-by-step explanation:
Let the hypotenuse = h , then:
h^2 = (3/7)^2 +(4/7)^2 ( By the Pythagoras Theorem).
h^2 = 9/49 + 16/49
h^2 = 25/49
h = 5/7.
Answer:
5/7
Step-by-step explanation:
We need the Pythagorean Theorem here.
If you have a right triangle, you can use the equation a^2+b^2=c^2 where a and b are legs and c is the hypotenuse.
Plug in your information.
(3/7)^2+(4/7)^2=c^2
Simplify what you can.
9/49+16/49=c^2
25/49=c^2
Square root both sides.
5/7=c
