Using the diagram shown, what is the magnitude of the resultant of these three forces?

i know the answer is 23.8 n i think because i looked it up but i have no idea how to actually solve.

Explanation:

The x component of the resultant force is the sum of the x components of the individual forces.

Fₓ = 65.0 cos 30° − 20.0 sin 20° − 30.0

Fₓ = 19.5

The y component of the resultant force is the sum of the y components of the individual forces.

Fᵧ = 65.0 sin 30° − 20.0 cos 20°

Fᵧ = 13.7

The magnitude is found with Pythagorean theorem:

F² = Fₓ² + Fᵧ²

F² = (19.5)² + (13.7)²

F = 23.8

magnityde and direction

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.
