Answer:
x =76.45 degrees
Step-by-step explanation:
72 + 252 – 2(7)(25)cos _x__=242
combine like terms
324-350cosx = 242
subtract 324 from each side
-350x = -82
divide by -350
cos x = -82/-350
cos x = 82/350
take the arccos of each side
arccos (cos x) = arccos (82/350)
x =76.45 degrees
That it is 4,6090 because when u divide that ,400 by 2,400 u will get 4,000
Yes it'll tessellate because if you notice the squares are only on the flat side of the hexagon and the triangles are on the corners
