the cosine of the angle of one corner equals the adjacent side divided by the hypotenuse.
the tangent of the angle of one corner equals the opposite side divided by the adjacent side.
The answer is c or the third option. If we start at one we get (4(1)-9)=-5, then we can do 2 and we get (4(2)-9)=-1. Lets do 3 (4(3)-9)=3. Now 4 (4(4)-9)=7. Now 5 and our last one (4(5)-9)=11. Now notice we get -5+-1+3+7+11.
Either 7x or -3x hope this helps hun!!
I believe the answer is x⁢10 if it’s incorrect i’m so sorry
