Pleasee someone help me

an angle that measures -425 is drawn in standard position. in what quadrant does its terminal ray lie?

the tip of a pendulum travels through an arc of 2.5 feet. if the pendulum has a length of 5 feet, through what radian angle does it rotate?

determine, to the nearest degree, the measure of an angle whose radian measure is 3.5

please help? I've never been taught this. :(

Hey,

I made a graph of the first question you can see here, it lies in the bottom right quadrant:

For part two, ArcLength = radius*angle

.'. angle=AL/radius = 2.5/5 = 0.5

For the third part, I think of it as each amount pi=180 degrees

So for any quest like this you can say:

x radians * 180 degrees / pi radians = y degrees

For your question, 3.5*180/3.14 = 200.63


Edit: fixed a ****** up part in the second ques.
Hope this helps
