Find parametric equations for the line. (Use the parameter t.) The line through the points 0, 1 2 , 1 and (4, 1, −5) (x(t), y(t), z(t)) = Incorrect: Your answer is incorrect. Find the symmetric equations. 2x − 2 = y − 4 4 = z + 5 − 6 4 + 4x = 1 + y 2 = −5 − 6z x − 4 4 = 2y − 2 = z + 5 − 6 x + 5 − 6 = 2y − 2 = z − 4 4

By pythagorean theorem,

hyp^2 = x^2 + h^2

hyp = hypotenuse = 5 ft.
x = ?
h = height = 3 ft.


5^2 = x^2 + 3^2
25 = x^2 + 9
25 - 9 = x^2
16 = x^2
sqrt(16) = x
x = 4 ft.

the answer is 4 ft.
