Question

Find the angle if Fx= 0.69 N & Fy= 8.35 N

Answer 1

Answer:

You really should not pose your questions in shorthand. This is my guess at what you wanted to ask:

“If a force F has components fx = fy = 6N, what is the angle between force and x axis?”

Draw a square with one corner at the origin of the xy coordinate system. The side that lies along the +x axis is fx and fy is the side along the +y axis. They are equal in magnitude and both are 6 N. The resultant is a vector drawn from the origin to the opposite corner of the square. You have 2 triangles. Both are 45-right triangles. So the angle between force and x axis is 45 degrees (or pi/4 radians
