Step-by-step explanation:

Given

--- scale factor

See attachment for triangles

Solving (a): The relationship between the angles of both triangles

The sine of an angle is:

By comparing the above to

Using Pythagoras theorem:

So, we have:

Collect like terms

Take square roots

--- approximated

For angle X, we have:

So, the relationship between both triangles are:

Solving (b): How to find CB and AB

In (a), we have:

For angle X, we have:

This implies that:

is dilated by scale factor 2 to give

So, CB and AB of are:

the correct answer is $7.38
