Pythagorean theorem 19^2 + 21^2=x^2

x = 28.32 units.

Step-by-step explanation:

Given:

Longer leg = 21

Shorter leg = 19

Hypotenuse = x

To Find:

Hypotenuse = x = ?

Solution:

Pythagoras Theorem States that

Substituting of the given value above equation we get

Step-by-step explanation:

Given:

Expression for Pythagorean theorem:

By Pythagorean theorem (applied to right triangles only):

where represents hypotenuse or the longest side of triangle, while and represents the other two sides of the triangle.

Solving for hypotenuse i.e. in the given expression

⇒

⇒

Taking square root both sides:

⇒

∴ (Answer)

answer: a rhombus has two lines of symmetry that run through one vertex to the one directly across it. unlike a square, planes through the center of each edge of a rhombus do not yield mirrored sides.
