Solution:
Weight of person = 179 lbs
As given person needs IV Drip in m L.
Also,→ 10 mg = 2 m L
Now, you must remember , → 1 lbs = 0.453 Kg (approx)
→179 lbs = 179 × 0.453 Kg = 78.47 Kg (approx)
The person needs at least 60 mg for each Kg they weigh.
⇒ 1 Kg → 60 mg
⇒ 78.47 × 1 Kg → 78.47 × 60 mg
⇒ 78.47 Kg → 4708.2 mg
Also, 10 mg → 2 m L
⇒ 1 mg →
m L
⇒ 4708 . 2 mg →
m L
⇒ 4708 . 2 mg → 941. 64 ml
For this case we must find the value of "x" that meets the following equation:

We subtract
on both sides of the equation:

We simplify:

Finally, 
Answer:

The total sum of angles at a point is 360, so basically just minus 360 by 90 and 60, and u get k, which is 210 °
