Can someone help me on this I’m struggling to figure it out...

In triangle opq right angled at p op=7cm, oq-pq=1 determine the values of sinq and cosq

Need on this geometry question. explain how you did it.

Sketch the vector field vector f( vector r ) = 8vector r in the xy-plane. select all that apply. the length of each vector is 8. the lengths of the vectors decrease as you move away from the origin. all the vectors point away from the origin. all the vectors point in the same direction. all the vectors point towards the origin. the lengths of the vectors increase as you move away from the origin.
