See the attached form. Problem 3 and 5. I have tried several times and can't seem to figure out how to get the angle in 3 and the distance in 5.
I got 5 with an answer of 5.0176 inches and it's 5.024 inches.
I STILL can't get 3 with all angles I can find and lengths.!!!!!
Thanks for any help given.

Are you not sure about the equation I wrote or how to solve it? Let x be the angle between y and . Then is the vertical coordinate of the center of the top circle. It is equal to 1.480 plus the vertical coordinate of the center of the rightmost circle. The latter is . In all this, R = 4.646.
To find y, divide both sides by R and take arcsine of both sides. What I get, though, is , not , as the answer seems to say.
You still have not said whether you understand why is true. Assuming you do, divide both sides by R = 4.646 to get . Taking of both sides gets . Since , evaluating the right-hand side gives , i.e., . Finally, , so .
If something else is not clear, could you specify precisely what?
