## Respuesta :

**Answer: 8**

**Step-by-step explanation:**

**We can use trigonometry to solve this:**

If we call the angle at the top Ф then x is the opposite and 8 is the adjacent

Therefore we use Tan to solve this:

Tan Ф = opposite/adjacent

Tan 45 = X/8

1 = X/8

8 x 1 = X

Therefore X = 8

Hold up hold up I believe it’s 86 no? Because the triangle is 180 unless of course I am wrong
