Question

find the exact perimeter of the triangle.
it's a right triangle with 4x on side A and x on side B

I don't understand what i'm doing and the lesson didn't help me.
answer choices are
a.68 sqrt x
b.sqrt 68x
c. 5x+x sqrt 17
d. 68x

Answer 1

so the missing side is h, the hypotenuse
h^2 = x^2 + (4x)^2 = 17x^2
h = √17 x

perimeter = x + 4x + √17 x
so, do you see that as a choice?

Answer 2

no but c is the closest to that answer
i think that may be the answer.

Answer 3

i'm not sure though

Answer 4

What do you mean it is "closest" ????
This is math, mine is equal to that answer!!!!
what is x + 4x ?????

Answer 5

5x

i'm sorry
