Answer:
14.
Step-by-step explanation:
this a addition problem since it says "overall".
you simply add them.
The length of each leg is unknown is first you would have to figure out how long each leg is, one leg is 30ft because of the 30ft on the other side. But since we don't know how long the top is we have to do 70 - 30 which is 40 now that we have both legs we can use the Pythagorean theorem 30^2 + 40^2 = c^2 the answer is 2500 and if we square it we get 50 hope this helps :)
76 is the answer, I put the answer in the photo below also!
Recall the Pythagorean identity,
Then we can rewrite the equation as
Factorize the left side.
Then we have
Solve for . We get two families of solutions:
and
(where is any integer)
