Respuesta :
remember Pythagorean theorem
if we have a right triangle with legs a and b and hytponuse c then
[tex]a^2+b^2=c^2[/tex]
we are given a right triangle with legs x and y and hypotohuse 10
so therfor
[tex]x^2+y^2=10^2[/tex]
[tex]x^2+y^2=100
solve for x
minus y² from both sides
[tex]x^2=100-y^2[/tex]
sqare root both sides
[tex]x=\sqrt{100-y^2}[/tex]
the answer is the 4th option
Answer:
The correct answer would be x=√100-y².
Step-by-step explanation:
You can use the Pythagorean Theorem to find the answer. That is how I found my answer.
