Answer:

option 2

Step-by-step explanation:

The problem can be solved using Pythagoras' identity for a right triangle.

The angle between due East and due North is 90°

The solution here involves using the Cosine rule.

let x be the direct distance between house and office, then

x² = 17² + 21² - 2(17)(21)cos90° → option 2

Note that since cos90° = 0 the equation reduces to

x² = 17² + 21² ← Pythagoras' identity

We need to leave m alone on the right hand side, so let's move everything else to the left hand side.

First of all, we can subtract b from both sides to get

$y-b = mc$

Now, we can divide both sides by c to get

$\dfrac{y-b}{c}=m$

And so we solved the expression for m, because we have written an expression in the form $m=\ldots$ , where the right hand side doesn't depend on m.
