Angle between radius and acceleration

[QUOTE="KristinaMr, post: 6053768, member: 649764"] [h2]Homework Statement [/h2] A particle is moving clockwise in a circle of radius 2.50m at a given instant of time. I have to find radiant and tangential acceleration and the speed of the particle. The acceleration vector is 15.0 m/s² and the angle between the radius and the acceleration vector is 30° [h2]Homework Equations[/h2] a tangential=∆v/∆t a radial =v²/r a =√at²+ar² θ=? [h2]The Attempt at a Solution[/h2] I tried finding the acceleration components but I was not able to use the data given in a proper way. I'm sure there is an equation involving the angle but I'm not sure which one it is. I would use θ=tan^-1( at/at) but it results in two unknowns . I'm stuck on this probably easy problem. I need someone who knows the right equations to use. Thank you [/QUOTE]
