Answer 2

Answer:

The angle made by the resultant with vertical θ = 38.85337415°

Explanation:

Forces 90 N horizontal and 72.5 N vertical represent components of resultant force Fₙ.

Now, fₙ can be represented in terms of unit vectors i^ and j^.

fₙ = 90 i^ + 72.5 j^

[Refer to the attached image.]

Let θ be the angle made by the resultant with vertical.

Now, tan θ = $\frac{72.5}{90}$

=> tan θ = 0.8055555

=> θ = tan⁻¹(0.805555)

=>  θ = 38.85337415° or 0.6781193 radian
