Given two angles that measure 50° and 80° and a side that measures 4 feet how many criangles, if any, can be constructed?
no triangle
exactly three unique triangles
exactly two unique triangles
exactly one unique triangle

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

      2

  2 is to go somewhat to the top right of a because it is squared    

v= a h/3

3 4 7 12 19

+1 +3 +5 +6

i would guess 26 because this isnt a sequential pattern or its to short to know
