**I'm having my semester test tomorrow, and I got this task from my teacher to do before the semester test.**

:

By decomposition of forces apply these formulas for a right triangle:

Task1:

An iceberg floats with the stream and wind. The power comes straight from the north with speed 3m / s. Draw this vector where the resulting speed of the iceberg to come forward as a vector. 1 cm shall be equal to 1 m / s. Calculate how large the resulting speed is using geometry or trigeometri.

Would be very happy if anyone could help me with this, thank you very much!!

**to the calculate resulting speed:**

How is this? and how do i draw this as a vector???
