What are the coordinates of the point where David wants to put the stake? Draw this point on the graph.

Which sum or difference identity would you use to verify that cos (180° - ∅) = -cos ∅? a. sin (α -β) = sin α cos β – cos α sin β b. cos (α -β) = cos α cos β – sin α sin β c. cos (α -β) = cos α cos β + sin α sin β d. sin (α + β) = sin α cos β + cos α sin β

Can someone check if i did this right since i really want to make sure it’s correct. if you do you so much
