Which statements must be true regarding the two triangles? Check all that apply. ∠M ≅ ∠M'' △LMN ~ △L''M''N'' △LMN ≅ △L''M''N'' The coordinates of vertex L'' are (-3, 1.5). The coordinates of vertex N'' are (3, -1.5). The coordinates of vertex M'' are (1.5, -1.5).

Aplayground merry-go-round has a radius of 4.6 m and a moment of inertia of 200 kg-m2 and turns with negligible friction about a vertical axle through its center. a child applies a 26.0 n force tangentially to the edge of the merry-go-round for 15.0 seconds. if the merry-go-round is initially at rest, how much work did the child do on the merry-go-round?
