3D Pythagoras Problems

##### 1 Answer

See answers below

#### Explanation:

Let

The bearing of X from Y is

It's the length of the longest diagonal

Driver A is at

Driver B is at

angle

The triangle

Therefore,

Angle

So,

We have a right triangle

Distance of bottom of ladder to base of wall

Distance of top of ladder to the base of the wall

Therefore,

Distance of top of ladder to the base of the wall

The longest diagonal is

The answer is

We have a right triangle of dimensions

Therefore,

In triangle ABC

In triangle AME

The height is

Let

The diagonal

Half this diagonal

In triangle

Therefore,

The side of the square is
