Interior angles of a triangle measure 180 2w + w + 90 = 180 3w + 90 = 180 3w = 180 - 90 3w = 90 w = 90/3 w = 30 so m < F = 2w = 2(30) = 60 and m < H = w = 30 =========================== u got 14 right... =========================== 15. Remember that angles in a triangle add up to 180. So triangle BAC......20 + 75 + m < B = 180 95 + m < B = 180 m < B = 180 - 95 m < B = 85
These triangles are similar, because if u did the same thing for the other triangle, u will find that both triangles have the exact same angle measures.
