**Answer:**

See explanation

**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:**
