(0.625T)╥(0.0250m)^2 *cosine of angle x = 1.00*10^-4 T*m^2
Solve for x

This came out of my physics textbook, so I already know the answer is 85.3 degrees; however, I do not know how to do algebra with trigonometric functions. If someone could just show me how to rewrite this, it would help me a lot.

Is that really the right answer? and question?
I keep getting 1.489 wth

The answer is right, but I may have typed the question wrong...

The formula for magnetic flux is

Φ = BA cos θ

B=0.625T
A=pi*radius^2 since this is the area of a loop. The radius is 0.0250m.

The question is "At what angle is the flux in this system equal to 1.00*10^-4 T*m^2?"

I'd help, but we haven't learned this yet in my physics class.

You do know 1.489 radians is 85.3 degrees right?
