If x is 20' and y is 30' how many feet is z?

Question

x and y form a 90 degree angle and I want the answer to z in feet

Answer 1

You have not specifically mentioned what "z" is - but I am assuming it is the hypotenuse of a right angled triangle. That being the case:

z^2 = x^2 + y^2

z^2 = 400 + 900

z^2 = 1300

z = 10 * square root(13) = 36.0555... feet

Answer 2

If I understand your question correctly,
line segments x and y form a 90 degree angle, and from that point line segment x is 20' and line segment y is 30' then line segment z would be:
z^2 = 20^2 + 30^2
z^2 = 400+900 = 1300
z = 36.05551275

Answer 3

If x and y form a 90 degree angle and z is the line between x and y (called the hypotenuse), you find z by:

z = squareroot(x^2 + y^2)
=squareroot(400 + 900)
=squareroot(1300)
=10sqrt(13)

Answer 4

If x, y, and z are the sides of a triangle, and x & y form a 90 deg. angle, you use the pythagorean theorem(?):

a^2 + b^2 = c^2
20^2 + 30^2 = c^2
400 + 900 = c^2
1300 = c^2
36.05551275463989 = c

Someone correct me if I'm wrong.

Answer 5

I think you are referring to a triangle...Since x and y form a 90 degree angle, then this is a right triangle...
Z is called a hypotenuse and the formula to find Z is

x^2+y^2=z^2...After find the sum of the square of x and y...Find the square root of that number..That is Z..

Answer 6

All you have to do is 20 x 20 + 30 x 30 = 1300 and take the square root to get 36.05551275 ft. (36.06 ft. rounded)

This method is called the Pythagorean Theorem.

Answer 7

z^2 = x^2 = y^2

Z^2 = 20^2 + 30^2
Z^2 = 400 + 900 = 1300
Z = sqr1300
z = 36 approximately

Answer 8

60

Answer 9

z = √20² +30²
z = √400 + 900
z = √1300
z = ± 36·05551.......
Taking the distance to be positive:
z = 36·05551...feet.

Answer 10

60 feet
