[Right Triangles Only] Pythagorean Theorem: a² + b² = c²

  • a is one leg
  • b is another leg
  • c is hypotenuse

Step-by-step explanation:

<u>Step 1: Identify Variables</u>

a = 19

b = <em>x</em>

c = 21

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Substitute [PT]:                    19² + x² = 21²
  2. Isolate <em>x</em> term:                      x² = 21² - 19²
  3. Exponents:                           x² = 441 - 361
  4. Subtract:                               x² = 80
  5. Isolate <em>x</em>:                               x = √80
  6. Simplify:                                x = 4√5

The vector ab has a magnitude of 20 units and is parallel to the<br> vector 4i + 3j.<br> find ab.
stepladder [879]

The vector ab has a magnitude of 20 units and is parallel to the

vector 4i + 3j. Hence, The vector AB is 16i + 12j.

<h3>How to find the vector?</h3>

If we have given a vector v of initial point A and terminal point B

v = ai + bj

then the components form as;

AB = xi + yj

Here, xi and yj are the components of the vector.

Given;

The vector ab has a magnitude of 20 units and is parallel to the

vector 4i + 3j.

magnitude

\sqrt{4^2 + 3^2} \\\\\sqrt{16 + 9} \\\\= 5

Unit vector in direction of resultant = (4i + 3j) / 5

Vector of magnitude 20 unit in direction of the resultant

= 20  x (4i + 3j) / 5

= 4 x (4i + 3j)

= 16i + 12j

Hence, The vector AB is 16i + 12j.
